Pros:
Amenities. Anything you might expect from a city park. Bathrooms, shelters, playgrounds, walking/biking trails, ample parking.
Tees. Concrete tee pads on every hole are level and in good shape. Tee signs are located at the front of each tea pad (which pad varies between long and short pad), though several of the metal plates are missing from the concrete tee posts.
Navigation. Slightly confusing in a few areas. After hole 8, follow the fence line into the woods. After hole 15 head past hole 20 towards the baseball diamond into the area to find hole 16. Otherwise the next tee is visible from the previous basket.
Variety. A wide variety of shots required, a good mix of wooded and open holes, with even the big arm holes requiring some accurate placements. Many technical holes require pinpoint accuracy and line shaping with the monster number 10 giving me nightmares.
Length. Everything from short ace runs, big arm holes, and a grueling gauntlet.
Water. Good use of the creek that flows through the park, it comes into play and offers high risk opportunities while keeping a conservative route open. The water is generally clear and shallow enough to retrieve discs from.
Clean. The unique garbage cans almost make this park worth the stop in themselves, besides keeping the grounds free of litter. The park is well manicured with the fairways and tee pads maintained regularly.
Scenery. A nice southern MN wooded park with a meandering creek, is a pleasant if not very secluded feeling.
Leagues and Tournaments. This city has an active disc golf community with weekly leagues and tournaments fairly often throughout the year.
Access. Easily accessible off of I-90.
Memorable Hole. Hole 10, a grueling deathmarch, 400 some feet through a 15' wide tunnel of trees.
Cons:
No loops. The course doesn't really return near the parking lot to make convenient loop options. You could easily skip holes, or walk back to the parking lot of you had to cut a round short.
Elevation. Mostly flat with only some slight elevation near the end.
Not Beginner Friendly. This is a great course for aspiring intermediate players, rec players may get frustrated by the long technical holes and water hazards.
Other user areas. The disc golf course is fairly well isolated from the other user areas, though the walking path crosses through, several holes play near the park road, and wayward shots could find a wayward pedestrian, as always, be aware of others.
Not Maintained in the winter. *Doesn't affect my rating, but have been taking note of it now that I have been playing more and more in the snow* I had to break my own trail and play on snow covered tees in the winter months.
Other Thoughts:
Well worth the play if you're in the area, I'd definitely make the stop if traveling past on I-90.
