Pros:
This is a city owned park but all the maintenance and labor is done by a remarkable course crew. There are constant improvements in areas such as: walking paths, erosion control, fairway maintenance, benches and signs etc. CH has all the amenities one looks for in a good disc golf course -- concrete tee pads, trash cans, benches, practice basket, good tee signs. You can tell right away that this is a lot more than just baskets and concrete dropped in and neglected since course installation. Cedar Hill is constantly evolving and slightly better every time you play it.
Where a prestigious ball golf course stands out due to excellent scenery, landscaping and greens, an outstanding disc golf course needs to rely much more on trees and elevation to craft fairways that reward good shots and provide excitement -- and it helps to have some scenic views (hole 17) and beautiful putting greens (hole 2). Cedar Hill nails this. Fairways are well defined and challenging but not unfair. Holes range from densely wooded to moderately wooded, however several holes are 'open' enough to reach for max D -- but you will need to exercise some control.
The greatest attribute of Cedar Hill is the varying pin placements. This will obviously be lost on you if you only play the course once a year or less, but it is what makes this course elite. Pin placements at Cedar Hill can change the entire experience. I personally have not played a more versatile course. Most holes have three pin placements, several have a 4th and 5th as well. Various layouts could theoretically alter average scores by upwards of ten strokes. Adding difficulty is not necessarily what makes them exciting though, instead it is the ability to make a hole left to right, right to left, or dead straight, etc.
Cons:
I think casual players and newcomers may struggle with Cedar Hill's more challenging holes. I don't see this as a con, but judging by some unfavorable reviews it would seem that perhaps not all skill levels will get the same enjoyment out of this course.
If your distance is in the 300-350 range and you don't have a several shots in your repertoire (i.e. turnovers, flicks, tomahawks, etc) you may get frustrated with some of the longer more challenging holes. For instance holes 1, 2, and 7 require excellent placements shots just to be in position to think about getting a 3. Many can and do argue these are par 4's or 5's but that is a different topic.
Other Thoughts:
The mix of holes means you can pretty much be as creative as you want from the tee pad. Play the fairways, go over the top, or throw rollers, you will have options. A varied mix of elevation throughout the entire course, an elevated basket that can play on 7 or 10, amazing downhill bomb on hole 17, the most serene putting green you may ever come across on hole 2; these are just a few of the qualities that make Cedar Hill worth your time.
If you are coming to play in Nashville this is a must stop. If you live in Nashville and want to get better at disc golf, then make sure you play Cedar regularly and don't shy away from its challenges. I can assure you, there is nothing more rewarding then mastering this course -- or so I've been told I still can't get under par.
