-Lots of holes with a variety of obstacles/distances
-Tees made of concrete
-Holes change position often
-Lots of parking
-It's free!

-Very busy on the weekend
-Course tends to eat discs
-Can be dusty during the summer
-Can be muddy or flooded in the winter

-Every type of shot is represented in this course: long, short, elevation up/down, rights/lefts, mandys, corridors, over the lake shot, everything!
-First permanent course.
-Lots of old timers to learn from
-Once you learn the course you can play holes any way you want to, making it convenient to work on all aspects of your game. Note: try playing the back 9 backwards. Super-fun.

-Rich kids who take a casual game way too seriously. Save it for the tourneys, dudes.
-Garbage
-Drugs
-Noise
-Wild Bill unless he's been removed. He can also be fun depending on mood/chemical intake.

Stay away on weekends unless you get there early. It turns into a douche-fest around noon.

-A very large course
-Free admission
-Lots of parking
-diverse hole locations
-pins get moved from time to time
-distance shots

-no Tee signs so you have to bring a map. You can easily go to the wrong hole
-The first few holes you might encounter locals playing in a soccer field so you must watch your throw.
-No water fountains close by. Bring your own water.

I frequent this course in all honestly because of the lake shot. It is by far one of my favorite shots. You are basically shooting over a dry lake and if you fail to get it across you will be looking for your disc for a really, really long time in the brush. The back end does not have much tree cover so you are pretty exposed so bring a lot of sun block.
There are a lot of environmental hazards here and one can easily lose a disc in any one of the many bushes, trees, or leaf pile up, so keep an eye on your shot at all times. There is one specific hole in which you are shooting blind. If I'd have to guess I'd say around basket #6-#8. We usually have someone stand mid way through the fairway and spot where the loose discs may land.
Till this day, after playing many times at this course I can't come up with a conclusion on how many baskets there actually are. I know for sure there are more than 18 though.

- natural Californian terrain of dense scrub oaks and other chaparral
- plenty of tight wooded holes requiring accuracy
- frequent pin rotation
- tucked away in an arroyo, with nearly no pedestrian traffic

- can get crazy crowded
-could use a few long holes
- bring a disc towel. Gets dusty.
- this course eats discs. Oak trees have a knack for holding on to em, and thick brush along several fairways.
- hate to say it cause it's my home course, but I agree with a few other reviewers here, that this course has a lot of a-holes. My most notable instance of douchery was someone trying to fight me cause he spilled his 40.

Print a map and cross your fingers that the place is empty.

Lots of creative looks at a wide variety of shots.

I enjoyed seeing the location of old pin positions and hearing some of the course history from knowledgable locals.

The course has very good flow if you start in the right place. See cons

A couple of holes play practically blind.

In a couple of spots, the flow seems very odd.

Print out a map.

Loved it!

- Amazing views. Lots of trees.
- mixed distance and technical holes
- alternative holes in the back
- feels safe for solo ladies*
- water fountains

- tees are a tad confusing the first time
- you may run into divas
- portal potties

I will play here again.

After a day in the sun, it was nice to play a round in the shade. The course is on the west side of a valley with a lot of trees. Apparently this was the first permanent disc golf course. I was surprised at the technical design. I would have guessed that the first course would be kind of boring, but not so.

There are plenty of holes that force a certain kind of shot. The holes are short, but birdies are not gimmes. It looked like there were multiple pin positions on most holes.

The hexagonal tee pads are great. Plenty of room to throw any kind of shot you want. If you want to try out that 360-degree approach, go for it (you might overthrow the hole, though).

The course is named Hahamongna. I love the sound of that, especially if I imagine Fred Armisen saying it as part of The Californians.

Navigation was not simple, even with a map. There are plenty of holes not visible from the tee, even with the short distances. I never did find the basket for one of the holes (14 or 15, I think). Several of the holes require walking back up part of the fairway to get to the next hole.

There was only one tee sign (very old), which makes me think there used to be more.

I could see this being a course that is enjoyable to return to once you know the layout. There aren't many holes here that have anything you haven't seen before, but for a piece of history in the shade, it's worth a visit.

History history history, the park is set amongst really cool old oak trees. Lots of different alternate holes and we played them all. Its like a little oasis in the middle of chaos.

Signage, they have a map at the ball diamond back stop but it really wasn't helpful at all. I used my iPhone to bring up a better map from the net. Hardly any grass but its its what it is.

Was in Cali in Oct so we had to make the pilgramage to oak grove .glad we did. Had fun time, not crowded, pretty backdrop of the mountains as we played some really cool shots. Overall glad we played here where it all began. I would recommend hooking up with a local as all the alternate holes that you really have to play can be hard to find as signage kinda sucks. Its a must play in the la area

-awesome scenery
-awesome locals (Thanks Adam, Mike...Chris, Frank, Cro, Tim, Ren)
-challenging, unique shots
-most tees are concrete hexagonal-shaped
-Highlight holes:
-hole 4: this one is tricky because according to locals, it used to be an open fairway before a storm knocked over one of the oak trees. I felt that the fallen oak tree made the hole that much more challenging and more interesting
-hole 4 (alternate): spider hole, a uniquely placed basket in the middle of a tree trunk with branches surrounding the basket. Must shoot from alternate tee pad (more or less a patch of dirt with a path going uphill)
-hole 5 (regular and alternate): from the normal tee pad a cool shot, but have the locals show you the "alternate" tee pad (which you can walk towards from the spider hole at the top of the hill of hole 4's alternate position). The alternate shot is easily one of the highlights of the entire course if not the best hole
-hole 14: another of the course's highlight holes. Shooting over the drink (or mucky muck...when I went the lake was semi dry and muddy). Also a kind of downhill "top of the world" type of throw, but you can also throw a big hyzer or anhyzer. I was surprised that some locals elect not to throw this hole. If you come here don't pansy out, you have to throw this hole in the name of Oak Grove.
-hole 17: This one has a double mando between two trees, with a third tree in between the two mando trees...a tricky, yet entertaining shot with a beautiful tree and rock lined fairway.

-lack of signage (no map, no reliable tee numbers, and lots of times no basket numbers either), a really really huge con
-difficult to navigate, especially without a map
-a couple tees were uneven cruddy rubber mats

It felt like I was experiencing a piece of history being able to play this course (1st permanent DG course ever in the world!). Super friendly locals was another great thing about Oak Grove. I felt that this place was a great mix of both distance and technical shots, but moreso technical shots. It helps to have both a forehand and backhand here. Must be able to throw straight shots to hit narrow gaps with low lying canopies and the ability to throw downhill on both holes 5 and 14. Midrange is very important here because many times you will hit a tree and need a good upshot. I never felt that a roller was necessary here, but that's not to say it couldn't be useful.
If this place had signs on each hole and better navigation, I'd give this place 3.75 or even a 4. But it gets 3.5 for the navigation issues and lack of hole information. Because the current course is not the original course, the numbers on the teepads do NOT correlate to which hole you are on necessarily, so keep that in mind. Baskets are old, some are missing the inner chains, but they do the job. Baskets sometimes are lacking hole numbers too. A quick fix would be to stencil the hole numbers on both teepads and baskets. Even some of the locals I played with had trouble keeping track of which hole we were on.
Overall a great course to play on, I'm glad that I completed the pilgrimage to the holy land of disc golf and if I'm ever in the area again I would not hesitate to play this course. Thanks again to the friendly locals who made this experience much more enjoyable!

-great elevation changes
-wide array of hole lengths
-holes are evenly spread out for left handers and right handers.
Wooded area has a great vibe due to dry creeks throughout many holes. During winter thaw they might be filled with water, I dunno.
-Bathrooms are spread throughout the course. There's real ones at the bonus "spider" hole, porta-pottys at the basket for 6, and a real bathroom at hole 17.
-i was able to find a course layout on the interweb, which would help if you are going for the first time.

-no pro shop, I wouldn't expect there to be one in this park though. You'll know when you see it.
-a few tee pads are in need of replacing, but still playable.

If you can join some locals to show you around the layout and possibly play the extra holes, I recommend it. otherwise you might get lost.
This course was perfect for ace runs on about 3/4 of the holes if you can throw 300'. Guestamation.

I loved playing this course, and when I get more rounds on it it will be awesome. I birdied a handfull, and also got fives on a handfull because there are a ton of trees, and some hillsides here. It's like playing in the woods at a campground because there is actually a camp there, looks like a summer camp for kids. I dunno?
Definitely come play here if you are in southern CA.

A wide variety of shots some downhill, around trees and various obstacles.
Free to play.
Easy to naviagate.

Not rough on the feet, no thorns, cactus, or stickers.
Hexagonal and rubber teepads worked quite well.

Dusty and Hot in the Summer
Very very tough to navigate if you've never played
Easy to lose a disc in nome nasty nasty brush
No shop or stand to get refreshments

Nice Technical Course

Tough course for power players
Real secluded feeeling in some areas and great great foliage.
Good use of the area and a great mix of technical and a couple bombers you can let loose on.
Great use of dogleg rights/lefts
Nice locals

no Bathrroms from what i remember

i love Oak Grove as i have a bad technical game and this course forces me to throw accurate. I love the secluded feeling and the scenery with the trees, yet i hate the spider webs you walk through getting an errant drive HAH. Many holes have multiple routes but very few are easier than the others.
If you find a local who's willing to show you the course you'll have a great time but bring water. I've heard there is poison oak but i havent shanked a drive bad enough to have a run in with it, but be prepared just in case.

-First permanent disc golf course. How do you not throw here if you're in the LA area?
-Pretty technical and challenging at times, especially given it's age. Oak Grove is by no means an "every disc in your bag" type course, but you'll have to work for your deuces and/or pars.
-The locals are great. They were very friendly and helpful when I played.
-Nice view of the mountains and NASA's Jet Propulsion Laboratory on the back 9.
-Nice variety of wooded holes, open holes, and even desert-like holes. I felt like I was playing in the midwest, the plains, and the high deserts of Utah all on one course.

-Nonexistent signage. Really. There are no signs indicating which hole you are on, where you're throwing, or where the next tee is. Your best bet is to wing it or follow (or join) a group playing ahead of you to know where you're going.
-If you're playing during a soccer match, you'll really have to watch it on the front nine. Some fairways butt up against the soccer fields.
-There are horse trails along the course, so there are points when your disc could land in horse manure. You could choose to think of this as a kind of water hazard, but that won't change the fact that you'll have a manure-covered disc if you get unlucky.

I've played a few courses made in the early days of disc golf, and they always disappoint after I get past the novelty of history. Not at Oak Grove. It's a fun, challenging, beautiful course, and I'll definitely play it again when I'm in the LA area. While it's not the best or most challenging course, it's definitely worth a round or two.

-Oldest course, great history!
-Plenty of shot variation, hyzer, anhyzer, a few rollers, a few holes to bomb it on.
-Nice atmosphere, plenty of friendly locals to point the way, guy sells used discs in the lot is also lost
and found.
-Not that busy the half dozen times Ive been out here. Great to get a round in with out too much waiting.

-People doing other activities, between soccer players, hikers, bikers, bird watchers, joggers, and today people on an Easter egg hunt you never know who is going to wander into a fairway. Always have to keep an eye out when teeing off.
-No signage, and confusing wrong numbers on the cement tees can lead to alot of confusion if you come here without a map or guide.

Between the history, the atmosphere and the course in general OG is an great place to play a round. Bring some water, and a map/local and you can have an awesome day.

Oh yeah and when birdwatchers stand 15 feet in front of a teepad staring into the trees with no clue of what is going on, don't worry they'll move eventually!

- Where it all began!! If you live in SoCal or are in the area you have to make the pilgrimage to the worlds first disc golf course.

- Holes are short however technical holes with clearly defined fairways.

- All holes have multiple pin placements, which can really change the feel of the hole.

- Unique hexagonal tee pads.

- The course offers a good mix of hole layouts, you can't get away with a hyzer on every hole. And the distances are are varied enough to keep things interesting

- An excellent DG vibe. You can tell that the course is well cared for and has a strong local club presence.

- Navigation is really a pain for the first time. PRINT OUT THE MAP. Or better yet get a guide. It is a really fun course, however it can get frustrating because there are no tee signs and the pads all have the old numbers on them. This is by far the biggest con of the course and can be easily avoided if you come prepared.

- A lot of holes play really short, and mostly pretty flat.

This is a must see for the history alone. But on top of that it's a really fun course that's worth playing over and over. It serves a great place to take begginners but also run into a few pro's.

I absolutely love the tournament layout for this course. It totally changes the feel, adding some serious distance to the course, while maintaining the technical feel of the holes.

Hole 14 has a signature feel to it. My first time playing I didn't see the water below and parked it for an easy deuce. Since then, and realizing the water is there I haven't hit a deuce there in over 10 tries, hows that for sport psychology.

The very first course in the USA!!
Local course pro, Johnny B making non locals feel right at home.
Technical, tight lies.
Warmer than Alaska in November!!

Not sure if I would have found my way around if I hadn't been playing with Johnny B and some other locals. Not very well marked.

I started playing 4 years ago in Alaska and have played 3 different courses up here. It was nice to compare our courses to the lower 48, especially the first course in existence!

*History! As it states in the title, this is where it all began. The first disc golf course in the world and it happens to be in Pasadena, California. Established in 1975, this course has been redesigned multiple times over the years. However, the first basket hole can still be played on hole #10 when it is located in the short position.
*OG has unique and diverse terrain through old oaks and desert landscape, including a lake on hole D. Great use of what elevation they had.
*Short technical course w/ low tree canopies yet multiple approaches through medusa like branches toward the pin.
*Large, sturdy, hexagonal tee pads, with the exception of the rubber mats on holes C and D. Multiple pin positions on every hole.
*Good flow allowing for multiple stops at the parking lot if needed. Especially helpful on hot, congested days. Multiple bathroom areas although not easy to spot from the hole one.
*The alternate/temp "spider" hole that plays uphill into the center of a tree with what looks like spider legs blocking a heavily guarded basket.
*Strong local club that has pro/am weeklies as well as large annual tournaments.
*Challenging enough for all skill levels making the replay value high.

Favorite hole/s: #1, "Spider Hole", "Lake Hole D", #18 (third to last hole)

*Also hit an ace on the "local" filler hole which plays after the "spider hole", throwing from old tee 17 to basket 4. Fun little 100 foot downhill shot.

*There are no tee signs or markings making navigation difficult for visitors. Tee pads also have the wrong number on many of them due to the course being redesigned multiple times over the years.
*The majority of holes on the course are less than 300 ft. w/ only two holes reaching near 400 ft. That doesn't bother me as much, especially considering it was built in 1975, but it may be for some.
*Lots of activities on the grass field near the first three holes, including soccer, football, or summer camp activities. Fortunately, they seem to comingle with the disc golfers. Just be courteous.
*No pro shop like Sylmar where players can get food, discs, and merchandise. However, there is an old school disc golfer named GW who runs the AM weeklies who sells club cfr discs at a reasonable price. He is a classic OG original and can tell you all about its history.
*Older mixed baskets that have seen better days due to heavy traffic. It was cool though to see the Iron Maiden near hole #10.

Least Favorite hole/s: #8, #9, #13

*Being a California native, the thought of not playing the world's first disc golf course would be both tragic and sad. After 11 years of playing I finally had my chance! Learning on De LaVeaga, and although on the opposite side of the state, I felt at peace as if I were back home. Due to the courses deep roots, the people who play OG are as diverse as the course. The original "good ol' boys "mixed in with the generation X and beyond. And yet... it seems to work.

*Special shot out to Snappyfingers, and HeizerSoze from dgcr for showing me around this magical place. It just wouldn't have been the same if I had played solo, and to play with people who were so passionate about OG was perfect!

**A must play if in the greater LA area**

Another great trip to the original course grounds. I really like visiting this park. Its a nice cruise through the course. Perfect natural landscape for a disc golf course. Short but technical with a lot of different throws required.
Throw one over the pound and don't

What happend to the Extra bonus holes for those that new how to play them. 4 years ago I played with a local that took me on the extended course. It wasn't there.

Some tees could be longer, I used to longer placements (but hey, it is the original course). Sometimes you are throwing on the group at the next Tee in front of you, causes hold ups. Not much else, I still haven't got my best round in yet. I will be back.

Throw it over the Pond! Don't wimp out be an itty bitty. I don't have the longest arm, but I ain't scared. I partnered up with a local and he keep telling me through the round that he didn't want to loose his disc. I told him it's all part of the game and they come and they go. Didn't make it on that round but I tried (went right and down in the brush on the ledge). But the last one, I put 40 ft past the basket. I watched groups after to group pass this hole up and opt for the alternate safe basket on the side. Go for it and show them how its done.

Outthink the crowds,pick your time wisely. I have always find a time when courses are crowded. I played 2 out of 4 rounds, I played right through, the others I didn't have to wait to long and met a few people.

Johnny B, dives for disc in the pond and has them and sells other used disc. Nice meeting Johnny B, good to swap stories and meet new golfers. Thanks

A wide variety of shots some downhill, around trees and various obstacles.
Free to play.
Easy to naviagate.
Hole 14 is excellent, one of the best holes ive played.
Not rough on the feet, no thorns, cactus, or stickers.
Hexagonal and rubber teepads worked quite well.

Not clearly marked, most tee pads have wrong numbers.
No relative distances marked and sometimes you cant see where the hole is, can make first time playing difficult.
No pro shop, snack shop, guide area to find out where to start (thought this shouldnt be that hard.

This has been the best course i've played thus far here in southern california, I didnt bring any water which was a huge mistake, by hole 15 I was dying out there, so make sure your well hydrated beforehand as well. If you go play there and its your first time ask the people around where to start everyone was quite friendly. It may be difficult to navigate the back 9 but this is only for the first time you go there, once you know its actually quite simple. ENJOY

Offers a good diversity of shots. Most are technical, not big booming throws. Wonderful setting. Good maintenance. Locals are chill.

Old mismatched baskets. Homeless guy on the back 9. Dusty in summer.

Can't beat the 5th hole during sunset... Unless it's the 14th hole after a huge storm.
