This course is in an old salt mine outside of Saint Louis. It's a really fun time if you're able to get a round in.

Because it's underground, the course is a solid 55-65°F year-round. Definitely a unique course.

Your discs will get eaten every time they hit the walls -- and they will hit the walls.

The course is mostly dark, so you will need lights or glow discs.

It is a small bit difficult to navigate.

This is a fun course through an old salt mine. It flooded several years back and they've brought it back since I played it last.

If you're able to get a round in here, you should definitely fit it into your trip itinerary, just make sure you bring a set of discs you don't mind leaving with major chunks taken out of them.

- Crystal City, occupying an abandoned sand mine, bills itself as an "entertainment Mecca" with subterranean takes on various activities such as volley ball, laser tag, boat tours, video games, an "archeological" dig area for children, and of course, disc golf. LED lights are sold at the entrance with tape provided for free. Beer and alcohol (as well as the usual array of snacks and non-alcoholic drinks) are also for sale and can be taken along for the round.
- Being a former sand mine, the walls and floors of the "cave" are far less rocky than you'd think. The walls were formed out of a crumbly sort of sandstone, and not some super hard granite or similar type of rock. The floors of the mine are amply covered with fine white sand like you'd find at a beach, which is a nice sort of touch (although you'll be finding sand in your gear for the next couple of weeks at least). I'm still trying to get it out of my discing shoes. I did NOT find that the cave excessively wore discs, like some seem to believe. I guess if you hit every wall in there, sure, but hit most of your lines halfway decently and your discs will be fine. It even seemed as though the sandy composition of the walls were softer than hitting some trees. A couple of wall hits made almost "hollow" sort of thumps as if the walls were nothing more than fake scenery at Disney World.
- Use of elevation and water. Both were present to some degree. I felt the water was not used to its full potential, but it also seemed as much of it was only there due to flooding (one of the 18 hole courses was almost completely submerged according to the guy working the bar). So perhaps this course is usually dry? Elevation was used to create a few decent raised basket areas, and enough slopes, rises, and falls in the passageways kept things from simply being tunnel golf. I wish there had been more of an effort to create more raised tee pads (I don't really recall more than maybe one throughout the entire 18-holes).
- The novelty factor here is through the roof. Not technically stunning disc golf design, or anything of that sort, but a super fun time if experienced with a good group of friends while kicking back some brewskis. You might not ever go back after the first time through, but it does seem like a course everybody should play at least once, simply for the experience. The added ricketiness of the lighting and its close proximity to the rising waters make this adventure golf just for the sheer fact that you never really feel comfortable that the lights are going to stay on the entire time you're down there.

- Amenities, other than the awesomeness of legitimately being able to purchase and drink beer while discing, are sorely lacking. Yes they offer LED lights and tape. Yes they have other activities. Yes there are port-a-johns both in- and out-side and a fire pit on-site by the parking lot. Baskets are lit up reasonably well with rope lighting of various colors, which is a nice touch. Much of the cave is left dark to good effect. Enough light to see but still keep large portions of the holes in the dark. The tees are lit mostly by white 50-gallon drums which are illuminated from the inside and crudely marked with the hole number in sharpy. Some tee areas had pads, while others were just sandy patches next to the drum. Signage was pretty much non-existent. There were several instances where it was not immediately apparent where to throw, and a detailed sign would help greatly. To be honest the course felt rather slapped together, and then left to just kinda deteriorate versus making continuous improvements.
- Crystal City is located in a super sketchy looking neighborhood, fo' realz. Definitely one of the most apprehension-inducing approaches to a course I've personally experienced. Cross a rickety old one-lane wooden bridge, pull into a dicey-looking parking lot, and head down a hole into the earth....yeah. I kept waiting for "Crystal City DGC" to be a ploy posted online by a gang of thugs attempting to snare unwary disc golfers in a bad part of town, steal their lunch monies, push them down, and skin up their knees.

- In the end, the novelty factor just isn't high enough to elevate this course to its maximum potential and the aspects of the course that come up short (amenities, design, overall layout) all seem like they easily could have been avoided or rectified. Great concept, okayish execution, mediocre in the end.

-It's a disc golf course in a cave. This is the most unique course I've played and you won't find another course quite like this one.
-Pretty good use of the the cave features. Baskets are put in alcoves in the cave and placed on top of rock features within the cave.
-The tunnel ways of the cave make pretty good fairways. Some are more wide open and then there are a few tighter fairways, which is nice. The course includes some straight shots, a few doglegs left and a few doglegs right.
-Baskets are portable Gateway baskets, but catch pretty well. All of the baskets were lit up with lights, which made them easy to see in the dark cave. If the basket is behind a cave wall of something, there are lit white containers pointing toward the basket.
-While the holes don't require to much shot shaping, if you throw a shot offline and get a cave wall stuck between you and the basket, you will definitely have to use a few escape shots to save par.
-The cave is nice in cool, so it is a nice way to play a round with out having to deal with the heat and humidity of the mid-west.
-It's a glow round of disc golf that can be played during the day. I enjoy a round of glow golf every once in a while, so I found this quite fun.
-A couple of the holes feature water hazards.
-The counter where you pay for your round features a pretty good selection of food and drink options and also has minis and flashlights for sale. Everyone at the counter was very friendly and helpful.
-The course used the little elevation in the cave to enhance a few of the holes.

-The course can get a little repetitive at times. Due to it being a cave, all of the shots are basically tunnel shots, without a lot of room to air it out.
-Navigation can be a little tricky, especially since it seems the course has been re-designed a few times. Some of the lighted white barrels are marked with the wrong holes numbers. Just make sure you use the map they gave you and you shouldn't spend too much time wandering around the cave.
-Most of the holes on this course felt pretty short. I only used a mid-range and a putter on this course.
-Doesn't require too much shot shaping.
-The cave can be really dark. It didn't bother me, but if you are some one who isn't good with enclosed spaces or doesn't like dark areas, then I would wouldn't recommend playing this course. I definitely recommend a flashlight and attaching LED lights to your disc.
-Some people wandering around the cave were unaware of the course. Since it is dark it is not always easy to see other people in the cave, so make sure there is no one in the way before you throw your disc.

This isn't a world class championship caliber course, but it is a ton of fun and is really unique. As long as you don't take yourself too seriously and just enjoy this as a casual round, you will have a ton of fun. This is definitely a course everyone should visit sometime to enjoy the unique experience.

There's quite a bit more to Crystal City than DG, but since that's all I did...
• Fun and cool, but hard to describe in typical DG terms, because it's so different from a typical course.
• Fairways are basically sand, and defined by walls of rock. The course is comprised entirely of a maze of intersecting tunnels in what was previously a mine. Obviously lots of tunnel shots, but there's more interesting shot variety than I expected. While it lacks trees and brush, there are quite a few dogleg left and right holes with several playing around corners. They've created some risk reward with a few tricky pin placements. There are some holes that actually offer a couple of ways to reach the pin; an easier route that has no chance of a deuce, or a more extreme route where there's a slim chance of 2, good chance of 4.
• Some fairways play past an intersecting tunnel, and the tunnels are pretty wide. If your shot fades early or turns into the intersecting tunnel, it's like missing the fairway. However, recovery shots can be very tough because you have to work around a wall of rock... with a ceiling. You can't throw a spike-hyzer or OH shot to get over/around some trees or bushes and back on the fairway while advancing toward the pin. The good news is the ceiling's pretty high, so you can throw some fairly lofty annies and hyzers around the corner to give yourself a chance of saving par, rather than taking a shot to just chuck it back to the fairway... but walls and ceiling certainly do make for different obstacles.
• Crappy weather? Who cares?! You're playing underground!
• Can be fun playing shots off the walls and ceiling.
• Wind - a non-issue like no other place you'll ever play.

• Tee pads - they kinda suck to be honest, and the sand is so fine and fluid, it can be hard to get good footing for tee shots, and several were wallowy or bumpy.
• Navigation/routing: Course actually flowed pretty well, but keep in mind that you're playing in a dark maze of tunnels that all look kinda the same - it's pretty disorienting and sans visual cues, an ordinarily good sense of direction can fail. This makes tee markers and routing particularly important. Lighted barrels w/ hole # are present at most tees, but not all, so sometimes you're left wondering if you've arrived at the tee... or not. The map seemed like a cruel joke.
• Depth perception is compromised in the dark, so it's harder to "range" holes to choose your disc, and my map didn't have distances. Chances are any course you're playing a glow round on is one you've played a few times before, so you have a decent idea what disc you wanna throw and how... not the case if you're visiting here.
• Hard to find your disc if it lands upside-down and you can't see the light taped to the top disc (but that's no different from a normal glow round).
• Could use some longer holes - seems like they have the room for a couple.
• I don't mind the $5 entry fee, but how about getting the basics right? I'm fine with a rolled out matt for tees, but make them level, not bumpy. I actually like the bare bones simplicity of lighted barrels with the hole #, but have them at every single hole, and maybe even a few next tee signs. A decent score card with map and distances would be nice, or put the distance on the "tee barrel." Seemingly little things like this would really make a difference in the customer experience. This is such a unique and cool experience that DG tourists will go out of their way to hit this place. Too bad they don't care enough to step up and get the little things right, even if they feel gotta charge another buck to do it, because it wouldn't take much to make this a 1st class experience.

Crystal City can't help but be pretty cool and is quite literally is unlike any other course you've played. You may think it's not so different from playing a glow round on a course full of tunnel holes, but it is. Because it plays through and around a maze of tunnels, and the obstacles present challenges that are a bit different than what we're used to, you need to adapt.

Just to clarify: it's in a former silica mine (raw material for glass), NOT A CAVE... so if you're hoping to play around stalactites, stalagmites or other geologic features, sorry.

Scores all its points by being a totally different kind of DG experience. Set these holes up in a typical city park and it's probably somewhere around 2.0 (typical), but there's enough novelty, fun factor and cool vibe to warrant a higher rating. However, they really missed an opportunity to take it to the next level (3.5) by flubbing the basics, so 3.0 it shall be.

• Call and get directions. Don't trust your GPS to get you here, mine didn't (tried coordinates as well as the addy... neither worked for me). The guy said most people's GPS's lead them astray getting here.
• I suggest using plastic you don't care about - the walls are tough on discs, particularly drivers. My FLX Challenger was fine, but GL River didn't hold up well. My Ibex was great choice for this place -perfect for a lot of the distances, neutral enough for shaping the required shots and durable enough for the walls.
• Lots of fine, soft sand means no skips.
• Tape light on well - if sand gets under the tape you could have problems.
• Bring a flashlight and clip it to your belt loop with a carabiner - it'll be handy whenever you need it and you don't have to worry about dropping it.
• Seems like they change things around (for better or worse) from time to time.
• Be prepared to walk several fairways scouting ahead to spot the basket - particularly inefficient on the loose and shifting sand, and you're gonna get sand in your shoes, there's simply no avoiding it.

1. Variety. While lacking in topographical diversity and abundant foliage typical to disc golf, the course presents a decent mix of obstacles and "airways" ranging from straight to left- and right-finishing shots, as well as a few subtle elevation changes and some water shots (including a fun carry on one of the later holes). The prevalent sandstone pillars are used to create many multi-route holes. All baskets are within reachable distance from the tees, but not all baskets are necessarily reachable with the lines available, with a few exaggerated doglegs that really take a placement shot then an upshot. Playing with walls and ceilings offered a truly unique and unparalleled disc golf experience and gave new meaning to the DG term "tunnel shot," and it was a blast to watch some of the ricocheting shots. Any little change in elevation was used especially well with pin locations, and while there was no extreme uphill or downhill shot, the designers seem to have utilized what they could. Most other reviewers have mentioned "The Rabbit Hole," which is a standout hole and fortunately not an overused gimmick down here (though gimmicks might succeed in distracting from some of the repetition and blandness of the golf in general), and it is arguably the signature hole.

2. Equipment. Gateway Titans are in great shape; I wish we had these on courses all over Wisconsin like they do in this area! The rope lights didn't appear to affect the catching ability of any of the baskets. Tee signs, where they existed, showed some minimal information. Most tees were sand marked with either boards or rocks, or had a patch of carpet/Astroturf to throw from; while not an ideal teeing surface, it's not the worst if you can adapt, and indeed when I played Toboggan it involved teeing off from sandy patches of Michigan soil, so the tees here weren't much worse than a course that received a 5.0 rating from me.

3. Uniqueness. Disc golf in a freakin' cave! As a geology major, the combination of caves and disc golf was too much for me to resist, though I can understand the attraction of this place to all the disc golfers who don't necessarily care about geology/industrial relics. My wife and I and some friends have an annual tradition of taking a Memorial Day voyage to various disc golf destinations; for several years it was Highbridge, then we incorporated Flip City, finally last year making Ludington and Mason County our destination, and for this year we decided to hit Crystal City and whatever St. Louis-area courses we could hit, then do Lemon Lake. We drove down from Wisconsin and headed straight to Crystal City at around 9:00 instead of checking into our nearby hotel (there is abundant lodging in Festus). The drive up to the complex was awesome, and I was the only person who was aware of "the bridge," so when I pulled up to it my wife asked, "Are you sure you're supposed to drive over this?! Wait, maybe we should back up and check the GPS!" while I chuckled and stopped halfway through and said, "Don't worry honey, this is the right way." Driving through the tunnel to the parking lot added even more excitement, and it was busy on this night with some live music, a bonfire outside, laser tag, and a few groups playing volleyball. I snapped photos inside the entrance like a stereotypical tourist, just amazed for the first half hour or so while we wandered around, had a few warm-up drinks and chatted with the bar staff (there was another group from Colorado that had driven out just to play the DG, and the employees were impressed that two different groups had road tripped to play there; not many of the workers seemed to know much about DG itself), then made our way to the first tee. I've played plenty of night/glow rounds, but this again was a new and exciting twist to the familiar, with illuminated Titans lurking eerily down poorly lit tunnels and around dark corners (we had some discussion of the film "The Descent" to keep the adrenaline pumping). LEDs purchased at the entrance and taped to transparent plastic were sufficient (I don't think we had any incidents of the lights popping off after hitting a wall), though I also carried and frequently used my LED Mag-Lite. Underground water holes are another very original concept, and walking to your lie after the forced carry on #16 via a path flanking the pond felt like something out of a video game (like "Borderlands" or some first-person horror shooter); I guess only those who've played it (slightly buzzed on $3 cans of Shock Top) and can relate to this sentiment will know what I'm getting at with that, but that hole might actually have been my favorite. The fact that there are TWO full courses down here is a definite bonus; alas, I only had the opportunity to play one.

4. Amenities. Okay, nothing country club here except the bar, which is pricey but not outrageously so with a semi-decent selection of drinks. Ample parking, though I could see it getting crowded with multiple large groups going out for the various activities. For a wee or worse, you'll have to settle for port-a-potties (one of which, according to my wife and another female companion, was "atrocious"). Multiple other activities, mentioned above and in most other reviews, make this a place where anyone can enjoy themselves. It appears that the facility is open to change and improvement (especially looking at the older reviews), and business seems to be decent, so I imagine the owners will enjoy long-term success with this multifaceted "recretainment" complex and will improve the courses to meet the demands of serious disc golfers.

5. Cleanliness. Obviously if you're picky about sand, you might not consider this the "cleanest" place to disc - and you'd be right, so be prepared to get SANDY. But as far as litter, I didn't see too much with my flashlight, and the trash cans appeared to be used by most groups. The water wasn't gross, either, just muddy.

1. Navigation. Despite other reviewers' complaints, getting to the complex itself using GPS wasn't an issue; we used the lat/lon coordinates as opposed to a street address, which may or may not have been a factor. The course rating gets docked pretty severely in this department, even with the generous wiggle room I give them by default for being underground and having the nearly insurmountable obstacle of providing a well-lit 18-hole course as the issue wasn't just darkness. The map on the scorecard is crap (same one provided in the links on this page, although ours appeared to have gone through several more incarnations of poor photocopying and thus were even blotchier), and getting around can be a nightmare. Most tee signs were so rudimentary that it was almost preferable to just scout everything yourself. Lit-up barrels are intended to guide the way and show the next tee, but confusion cannot be avoided when you are surrounded by pillars and have a spray-painted arrow on a barrel pointing off into an ambiguous direction of various potential routes, and occasionally you'll spot the wrong basket before the right one. We got REALLY mixed up somewhere around #5 and #6 (or maybe #4, I don't remember), but the most annoying part was the number of holes that required scouting ahead to spot the basket - walking in the sand is a workout, so going back and forth down the fairways looking for the pin gets tiresome.

2. Design. I recognize the inherent limitations to creative design with this terrain; there just isn't much other than sandy tunnels and pillars with some water thrown in for spice. The golf challenge falls way short here, as the prime obstacle encountered by your disc will be the walls. Lacking are tight gaps and narrow obstacles, two key ingredients to a "good" course. Way too many shots that finished to the right (in fact, as we walked through the parking lot we encountered a family heading back to their vehicle and asked them about the course; the dad said, "All I can say is, stay right!"). Many of the blind baskets required a placement shot, then a boring upshot and a par putt. Not nearly as much "wow" factor as I had hoped, unfortunately.

3. Limited availability. One of the things I love about disc golf is being able to just go and play, usually whenever I want, including at night with only a few lights; Crystal City is open about 30 hours per week, mostly on the weekends from late afternoon/evening into late night. While I understand that as a business they would require paid staff to have the facility open, I think that to make this a true "disc golf destination" it will eventually need broader access including more weekday hours.

Ever since the announcement that there was a disc golf course underground on the DGCR forums, I have had Crystal City on my wish list. Was it worth the road trip?...Absolutely, even if my rating does not necessarily reflect that! But whether or not it is worth YOUR road trip is for you to decide, and that is partly why I write reviews; I would like to be as well-informed as possible before traveling a great distance to play a new course, and I was a reader of DGCR reviews before I was a Trusted Reviewer! Now, since I only got to play the North Course, would I plan another road trip to play the South Course? Absolutely not, unless the facility itself and the surrounding courses (ESPECIALLY completion of the anticipated Deer Creek multi-course complex) can draw me back. I wish I'd played some of the other highly rated courses like Jefferson Barracks, but time constraints and weather prevented much more course exploration on this journey. I love the fact that I can tell people that I played disc golf in a cave, and I will encourage my fellow disc golfers to make the journey to Crystal City.

There isn't a lot that can be done to the course to improve the golf other than improved tees and navigation, although I do have some suggestions to add to the experience: 1) Obtain some old telephone/cable poles (check with whatever utility companies are responsible or get some trunks from a lumberyard) and use these as vertical obstacles to mimic tree trunks both in effect on disc flight as well as effect on the plastic itself (hitting the walls repeatedly is, as noted in numerous reviews, pretty rough on base-plastic discs); I personally can envision hundreds of these implanted in a veritable underground forest, which of course is probably unattainable at the moment, but those kinds of obstacles mixed with some form of artificial bushes, and even a few more gimmicks like a creative mando or two, would go a long way in assuaging the repetition that this course suffers from. 2) For having such limited hours and being pay-to-play, I would expect some kind of CLEAR signage, glow-in-the-dark arrows on the cave walls or battery-operated LEDs, floor-to-ceiling netting to eliminate confusing intersections and create more discernible fairways, just something to a greater degree than what is currently provided. 3) Put in a course above ground! I remember reading that this was possibly in the works, and the terrain above looks like it would be fantastic, and a GREAT course up there would counteract the not-so-great golf down below and make this a place where serious traveling discers would spend an entire day or more.

One final note: Avoid "St. Louis Style Pizza" at all costs. Not only is their cardboard-like crust covered in tomato paste, they use some disgusting processed blend called "Provel cheese," and its only redeemable quality is its meltiness, but other than that it is pretty tasteless and was completely underwhelming even to a pizza glutton like myself. Sorry, STL, your pizza sucks.

It's really hard to give this course a "subjective" rating since there's nothing else to compare it to?

You HAVE to put this course on your bucket list. It is the most "unique" disc golf experience you'll probably ever have...
This is an old Silica Sand mine that they used to make glass (Crystal City). The mine was closed in 1986.
Day or night, whether the weather ;-) outside is 110º or -30º, snowing, raining, it's always a fairly humid 55º inside.

There are 2 courses:
NORTH easier and one water hazard,
SOUTH: Longer with water on about 6 holes.
You will get a pretty good leg workout walking in the loose sand for 18, 36 or more holes.
The Gateway Titan Portable Baskets are lit with Rope-Lights running through them.
The Tee marker Barrels are white plastic Barrels with lights inside of them.
>>>Hole #17, North Course, "The Rabbit Hole" Very Cool. Only 104 feet, but, you throw blind around a corner and through a 4 foot hole through the cave wall, go through the hole and to the basket.

>>>>This is a work in progress. With that said...
>>>>My biggest complaint and the reason I am dinging the rating is the navigation.
There were no maps for the North course which made it tough to even find the first hole, and, had to search for quite a few holes after that.
>>>>Mark the baskets and tee barrels with numbers to aid navigation...

There are lights but you'll still need glow plastic or lighted discs for some of the darker sections.
>>>>Bring a GOOD flashlight for navigation and finding your discs. a couple times we had discs bury in the sand floor enough to hide the light and would not have found them without a flashlight.

The cave walls, ceiling and pillars are sandstone and will EAT your discs. I just used some older Champion plastic discs and they held up pretty well. A DX disc would most likely be toast after a round if you don't keep it off of the walls.

There is also a 30 min. Barge ride (Pontoon Boat) on the 150 acre underground lake through the flooded parts of the mine which is also where the "South" course is located.

Inside the cave there is also:
A Bar
They have Bands
They show movies
Sand Volleyball
Laser Tag
Paintball
Air Soft
Golf Simulator
SCUBA Diving in the lake
Kayak Lessons

Kudos to the owners for having the vision to turn this property into an entertainment mecca with all of the different activities they currently have, plus, plans for lots more...

A really cool way to get some use out of this old "abandoned" mine

-The only subterranean course on the map!
-The owner now has portable Titan baskets in.
-Some very technical as well as aceable shots.
-Just got done with the second course.
-$2 bud lights
-They sell led lights if you need them.
-100 degrees outside/ 60 degrees inside.
-The owners plans are to put an outdoor course up too!

-The second course is not really ready for complete play, its set up but a lot of work is still needed to be done.
Last time i went it was $5 for unlimited dg, not it's $5 every 18 (which i don't really mind paying as long as its going to help make the place better).
-Sand tees (Bring shoes you don't mind getting messed up, and bring extra socks for the ride home)

-I have started to devote a handful of discs for this course that i've been calling cave discs. reason being the cave walls tear up the disc pretty good. So don't bring your favorite discs down here.
-Another thought is that yes we all know the signs and tees are bad but most of the time it's just the owner working on it all by himself back there. He's getting up there in age and between busting it in that cave and putting up with Crystal City, i give him respect.

It's in a cave.

Baskets - some cloth, some metal, kind of a variety
Tee Pads - sand, hard to get footing
BUSY = backups

There really isn't much to say about this. How often do you get to play a round of DG in a cave! If you're in the St. Louis area and have time, it is worth it just to play in a cave. I wouldn't bring my tournament bag because the walls will tear a disc up. Again, it's disc golf in a cave, until I see other places to do this, I have to give this a pretty decent review.
