Pros:
+Beautiful place. Rolling hills, meandering stream, lots of rocks, tight (but fair) wooded lines, picturesque stone walls, good bridges over the water, not very muddy...really a great experience. We had three young ones with us, and they entertained themselves for 2.5 solid hours while we played. Overall feel is similar to Clark's Run in VA or a mini Iron Hill.
+Get off the fairways and you'll be in trouble, but finding discs is not an issue. We had two low-intermediates and two beginners playing, and never looked longer than 10 seconds for a disc. Course is very well maintained.
+Holes were well-crafted and made superb use of the terrain. Not a junky hole in the whole 18. A few that were pretty memorable (#2, #8, #11, and #15 pop to mind).
+Two tees and two baskets per hole at all times. Course has excellent replayability value. Raised rubber tee pads are in great condition (note con below about rubber) and baskets are too.
+Different layouts provide widely differing challenges. Short-short is good for anyone; long-long (even short-long) will challenge even the best players.
+Has three open holes (1, 10, 18) that let you rip a disc without worrying too much about trees. These are well placed to give a good warm-up, break, and finish after wooded golf.
+Nice practice area with two baskets, picnic table, and lots of small trees to provide tricky putt practice.
+Set in a disc golf-only part of the park - as far as I could tell, there were no hiking trails through here, so no issue with hordes of pedestrians (this course is pretty remote anyway, though).
Cons:
-I'm always wary of rubber tee pads as they are death traps in wet conditions (and they might not dry quickly with 15/18 holes firmly in the woods). They were in fine condition on a beautiful September day, however.
Other Thoughts:
Located on the same grounds as the Churchville Rec Center. It was closed due to COVID, but I'm guessing there are bathrooms and water in there. It is a long walk from the disc golf parking lot (which, in turn, is about a 400 yard walk uphill from hole #10 tees), so do plan ahead.
As of Sept 2020, UDisc is off on the pars. Go with what you see on DGCR's hole info page.
If you have little ones in tow, recommend the superb Annie's Playground before/after the round. About 20 min away, close to I-95.
I definitely plan on coming back here from DC suburbs (1 hr 15 min from College Park) a few times a year. Worth the drive.
