Pros:
This is an incredibly challenging course that shares its space with an old ball golf course, although I've never actually seen anyone playing ball golf while out there.
You're really going to use every shot in your bag, and each hole provides different routes and opportunities for different skill levels of players.
Lots of elevation changes.
Great quality baskets.
Concrete teepads exist.
Most of the holes have accurate signage, although a few of the holes the signs have fallen down.
A really big range of hole lengths, with the shortest two coming in at about 200, and the longest coming in at a whopper of 1,111 ft. Most are probably smack dab in the middle of that in the 300-400 range.
When I say this course is challenging, I mean it! You will learn a ton about your disc golf game by playing here. There are places where playing it safe pays off, but also places where if you don't take a risk, you could end up with an even BIGGER score than if you do.
University Park is a great place to come out and get your butt kicked, and not feel bad about leaving with a 10+ over par.
Cons:
While the challenge is great, it prevents it from being an every-day course in my lineup in the way that some of the courses in town in Manhattan are. I really only come play UP if I'm ready to get roughed up by a course.
The rough is VERY rough. The cedar trees which constitute the rough for most holes can really tear you up, and there are plenty of opportunities for your disc go find itself there.
The course is a hell of a hike. I can't imagine playing this course twice in one day.
While the concrete teepads are great throughout, they are maybe just a wee short, which can be tricky given that this course requires monster drives.
If you can't drive over 300 ft (curse you my 290 ft arm!), there are some holes that are a little inaccessible. Hole 12 is a monster of a hole, and if you don't have a 300+ ft drive you're going to have a bad time. It's immediately followed by a hole with a rock wall 300 ft out, that the posted rules stipulate you must clear or head to the drop zone to throw for 3. A bit frustrating for players right at the edge of that distance level (cough, me, cough).
Hole 7. It's a par 5 that most people I know took an 11 on their first time playing it. You play down into a valley, then through some of the thickest woods on the course, then up a big hill, and around a tree. This is the hole that can make you want to rage quit disc golf if it goes poorly for you. For someone without a giant arm, you almost HAVE to cut this hole into 5 perfectly placed shots, and any movement astray in the woods will leave you in some serious rough without much of a line out.
Hole 7 will eat you up, and then is immediately followed by tricky hole 8 with a giant blind drop into the woods which can also be a big challenge if you're not great at going over the top.
Other Thoughts:
My above comments about the really challenging holes are something I almost wanted to mention as both a pro and a con. They are part of what makes this course challenging, which is part of what makes it great. But they can also be disheartening for rec and intermediate players. If you come into it with a positive attitude and a lack of concern for the fact that your score is about to be blown up, UP is a really awesome course to become a better disc golf player on.
