Pros:
Carrollton Park is an 18-hole disc golf course constructed on part of the remnants of a neighborhood that was bought out by the city of St. Louis for noise abatement. The buyout was for the newest runway at the airport, which sits just a few thousand feet from this course. This results in one of the more unique course environments you will come across.
The result of the neighborhood buyout is a disc golf course that runs along the old streets through the former yards and properties. This makes for a course that primarily has narrower fairways, requiring you to keep your drive between the streets and the lines of trees that used to separate the backyards in the neighborhood.
Being a course designed by Dave McCormack and Gateway Disc Sports, the baskets are Gateway Titans that are in great shape. The course has a kiosk and practice basket next to hole 1, with plenty of space (a whole front and backyard, you could say) to practice your putts. The kiosk has a detailed course map as well as information on the local leagues and clubs. Additional signage at the ends of the street point disc golfers coming in either direction to the start of the course. Each tee sign is very detailed with pin placements/distances, next tee directions, and have an aviation theme to them. I feel like the concrete tee pads get in on the aviation theme of the signage, because you could land a plane on the pads on this course. I've played 82 courses at the time of writing this review, and I don't recall seeing larger tee pads anywhere. There are also a fair number of benches, picnic tables, and trashcans throughout the course, especially on the front 9.
The setting of this course makes for a very unique playing environment. The former houses are gone with no evidence of their foundations, which provides some interesting terrain factors to consider. The land does have some elevation to it, but in a lot of the course, the old lots are individually leveled off. This means that a small different in height or speed in your drive can affect the distance you get to a higher level on this course. This doesn't affect the whole course, but some fairways like the ones on holes 5, 7, and 13 really highlight what I'm talking about. Hole 4 uses this interesting terrain to its advantage, starting off with a drive off the tee right above a big drop off between 2 lots.
The tree lines also add a lot to the shape of this course. Being a former subdivision that was built in the 1950s, there are lines of mature trees that run along every fairway on the course. While the land does have some upkeep in terms of grass cutting and other maintenance, a lot of the brush is still dense, providing plenty of incentive to stay out on the fairway. Some lots are also lined by trees on either side, requiring you to navigate around or through smaller gaps to get your birdie or par. There's even a couple of patches of dense bamboo along holes 3 and 13, which just adds to the uniqueness of the land.
I picked this course to play my most recent round at specifically because it rained the day before, and everyone on the local club's page said this course drains the best out of any course in the area. While there was the usual mud that most courses will have after a good rain, there were minimal puddles around the course, and the ones that were present did not factor into my round. If you're a St. Louis local, this seems to be among the best options if you want to play right after a good rain, since many of the other courses in town get saturated easily or even flood.
Each hole has between 3 or 4 pin placement options, with a lot of the holes providing a lot of variety. Hole 1, for example, has 4 pin placement options, ranging from a 250' par 3 to a 738' par 4. The variety of pin placements on this course can mean different shot selections on a given hole depending on what pin is being used, and means par for your round can range from 60 to 68. While this is one of the higher pars in the St. Louis area, the difficulty level/distances mean that recreational and intermediate level players can still challenge for or below par on this course.
Cons:
Having "park" in the course name feels like a big stretch. There are no park amenities or activities on the land except for the disc golf course. Do not come to the course expecting a bathroom. water fountains, or other amenities on site.
As many reviewers have suggested, the navigation leaves more to be desired. It's obvious that the idea was to get holes 9 and 10 back to the parking area, but the layout leads to some walks between holes that feel unnecessary. I'm not a course designer, and understand there's a lot of factors to balance. However, considering the fact that there's no parking area on this land except for the streets themselves, I feel like some better flow options could have been found on this land, perhaps while even keeping the two 9-hole loops available. As it is currently designed, however, it can be vital to check the tee sign for the next tee location before you walk to your drive. UDisc is a great tool to help you navigate the course, but I feel that you shouldn't need an app to navigate a course. A lot of the longer walks do have signage, but I had to pull out UDisc to find hole 15 since it was hidden behind some trees.
Some tee pads and pin placements feel like real head scratchers as well. While there's understandably not a lot of traffic on the roads, Gallatin Road and WoodFord Way do get some cars driving through. I think some pin placements close to the other roads are fine since they don't get through traffic, but some pins around the through-streets feel too close to the roads to be fully safe from drives or approaches. Some hole placements, like on holes 8 and 11, also run close to the busier roads on relatively tight fairways. Given how long hole 11 is, an errant throw can easily end up on the Gallatin. I have also seen a badly shanked drive flirt with the highway during a round; please be careful. The location of holes 9 and 10 combine with the location of the course start also means that your car will be in range of a bad drive off of one or both of these holes.
A couple tees and pins especially seem off to me around the neighboring apartment complexes. 12C is pretty close to an apartment parking lot, and considering it has a distance of 295', it's well within the range of many players to reach. This hole's location already results in a longer walk to 13, but being so close to parked cars feels sketchy. Hole 14's tee is also very close to an apartment building. The hole plays away from the buildings, but even if the tee pad is on city owned land, the tee is close enough to people's back sliding doors that it feels like the course is encroaching a bit. This course hosts multiple tournaments a year as well as league play, and this course gets enough play that I imagine this could potentially be annoying to the neighbors at times.
Other Thoughts:
Carrolton Park isn't a park; its land claimed by eminent domain that now hosts a disc golf course. The land the course sits on, along with more land just across the highway, once hosted 1,800 homes and multiple parks, schools, and churches. The airport expansion was more than a sore subject, especially for the people that once lived in Carrollton. Playing a round here can feel weird and unsettling for some, and for me, playing a round here feels like trespassing in a way. The aviation theme on the signage also feels like a weird choice to me given the history of the land, even if the proximity to the airport means you can regularly see low flying planes during your round. That being said, it's better to have the land being used at least a little bit rather than being completely abandoned.
Perhaps I'd feel more positive about this course if the city made the land into a park, but seeing as it's been 8 years and counting since the course went in, I wonder if such plans are or ever will be considered. The grass gets mowed at least occasionally, and the city removed trees on occasion for various reasons, so the land is at least on their radar. You won't find Carrollton on the city website though, so it's hard to say if/when more work will be seen on the land. I haven't been checked out the roads across the highway, so I wonder if that land is in better or worse shape.
Carrollton is by no means a bad course, and its proximity to other courses means you can easily make it a part of a disc golf day across west or north county. I think the current layout prevents this course from seeing its full potential, but recreational and intermediate players will a good level of challenge here. Higher level players will likely find plenty of birdie opportunities here.
If you're visiting the area, I would put other courses higher on your priority list. If you're a local and haven't been to Carrollton yet, it's worth a visit. Pair it with White Birch or Creve Coeur-Lakeside if you want some variety in a full day of golf, or with Endicott if you're a sucker for technical challenges.
