Pros:
Some mild elevation, a few trees for obstacles.
Cons:
Still very, very open overall, without any challenging shots.
The baskets are the defining feature of this course, and that is not a good thing. Even slow, floating putts can knife clean through and out the back, regardless of angle. My home course has handmade early-80s baskets that had to be retrofitted to double chains, and they are absolutely luxurious compared to Dublin Park. Missing a perfectly clean, slow putt that should have stopped dead is frustrating, and it is for that reason that I can't try to justify this as a beginner course. If that had been my first experience with disc golf, there might not have been a second.
Signage is lacking. Tees are numbered, and the baskets are too, but I couldn't even tell there were numbers on the baskets, much less read them, from the tees. Finding the next tee can be interesting.
Other Thoughts:
Natural tees.
Try not to bean any walkers and/or children on the playground.
Could very possibly be better as an object course. Never thought I'd say that.
If you do want somewhere in the area to play as a beginner (or to take a friend who's just learning to play), try Brahan Spring.
