Pros:
A perfectly pleasant and very short 9-hole course in a small city park.
The park itself is totally unobjectionable. Pavilions, parking, a walking trail and playground, and some trails wind through the reasonably thick woods. There's a creek and some elevation in play to make things more interesting. To add to this, the course designers installed wood frames and spray painted the walking path for tees, and added numbered DISCatchers.
The course is very short. If I were setting pars, holes (1)-(4) and (8) would all be par 2 in the 90'-120' range. The other holes are in the upper 100s and low 200s with trees, so still par 3's. Trees are omnipresent and require the thrower to correctly shape their shot (however short). Some are straight down a moderately tight tunnel, others turn right, others require a substantial hyzer, and a couple will require gentle fade to park it. Elevation comes into play with both uphill and downhill shots. The lines are tight enough to require decent release, but are all very recoverable due to length. There is also flexibility to choose your own shot on many of the holes.
Overall, I think it's a good course for its target market, which is players with about 5-25 rounds under their belts. They'll be frustrated at times, but at other moments will have a chance to park it. If there were another local course that were an open 9-holer, it would pair very well with The Hill to develop a beginner's game. It's easy-to-play, won't eat your discs, and is pleasant and moderately scenic.
Cons:
Limited length = limited potential. For golfers above novice level, this will be a total breeze. A rec player with a good woods game could score all deuces. As such, it won't have lasting appeal to very many players. As an example of a beginner woods course this is a 4.5-5.0, but in the continuum of all disc golf courses, I think it earns a Passable.
There were some smaller issues as well. A couple of the fairways look like they have drainage problems, leaving mud in their wake. The course doesn't loop very well, ending a long way from the first tee. The intertwining of the course with the walking trails will also necessitate waiting if it's a busy pedestrian day.
Not an issue as such, but hole (5) is disproportionately hard compared to the other holes on the course. It's the longest at 246' and requires a straight tunnel shot with gentle fade up and over a hill. An easy three, but I don't see a novice having any birdie look.
Other Thoughts:
There's not much more to say. The Hill is a nice place to learn how to play disc golf in the woods. Once you've learned, I don't know why you would come here (except as a course bagger).
