Pros:
The biggest pro for this course is the scenery. When you hear "plays around an abandoned mine" you might have in mind something much more rugged and industrial than what this course actually offers. When you approach this course, it looks like a very typical city park... ball diamonds, skate park, playground equipment. This is also totally deceptive in terms of your eventual experience. Hole 1 plays through a pretty standard woods hole. You then turn a corner and the course opens up onto a basin with a crystal clear, serene, and beautiful lake which you begin weaving around. Holes 2-4 are on a switchback which gets you going back around the circle that you eventually follow around the entire lake. The views were really breathtaking. Some absolutely gorgeous shots of baskets overlooking the natural beauty of this lake and its forested surroundings.
Hole 4 plays over the lake. It requires a big (RHBH) hyzer to get there, but a shorter hyzer can still play safe if you're OK with crashing into the rough short of the landing zone. There is a shorter drop zone, but that doesn't entirely remove the risk of a water landing.
The signs at the teepads are accurate and helpful. I found the movement between holes to be super intuitive. I was there alone (I was the only human being I saw on the entire course, which really contributed to the serene experience), but I did not have trouble navigating the course.
Really challenging elevation changes throughout the course.
Good quality baskets (I believe prodigy). Easy to see yellow bands.
Some really excellent risk/reward calculus on this course. The fairways are all pretty accessible. The shots don't look terribly challenging from the teepad. But if you find yourself even just a short distance off the fairways, you could end up in thick forested rough or 100 feet down a steep hill. The hill is especially in play on #2, the basin hole. I threw what I thought was a very safe shot, but even the slightest roll put me about 50 feet down hill and looking for a disc.
I would describe this course as "mountain-light" golf. The elevation changes reminded me of some of the Colorado mountain courses I've played, but you're not at mile high altitude, so it's much more physically accessible. There's definitely still a high level of physical demand with the elevation. You're going on a good hike no matter what. But I didn't find myself running out of breath on every hole in the same way that I do on tougher mountain courses.
A few makeshift trashcans and boulder benches near a few of the teepads. Quite necessary because I went through a few bottles of water and also needed to sit and rest for a few minutes in the middle of this hike.
Really great hole variety. A few big bombers, but mostly technical wooded holes. You've got one BRP-esque giant tunnel shot through a narrow corridor of trees right toward the end. In terms of difficulty level, I think the course starts pretty easy, then ramps up difficulty in the middle, and then gets easier on the last few holes.
I really can't stress enough how gorgeous this course is. I just kept turning corners and having my jaw drop at how naturally beautiful the surroundings are. This is destination disc golf at its finest. One of the best free courses I've ever played on. If this was a bit closer to major population centers, and had a pro shop and a few more amenities, I could easily see this being a 10$ pay to play course. It's that high of quality. As it stands, if you are anywhere in the area, I totally recommend coming to play some beautiful, challenging, but still accessible, and totally free disc golf.
Cons:
Not many. And the things that are negative are mostly things that add to the challenge of the course, so hard to really complain about it. Specifically, the rough is, indeed, rough. If you get off the fairway, it is really easy to lose a disc if you're throwing alone. I probably spent 30 minutes on hole 10 looking for discs. I would recommend throwing bright colored (not green) plastic once you get into the woods. But honestly, even this was not intolerable. The rough was hard to find discs, but I never felt like I was going through thorns or tearing my legs up to look. It was simply hard to find discs.
Also plenty of places to have a disc roll down hill. If you're not ready for walking on some uneven terrain, this course might not be for you.
Definitely look at the info on the DGCR front page for this course. If you follow your GPS, it takes your car onto the fairway for hole 1. No bueno. Instead, park right by the skate park and baseball diamond. You should see the sign for the course at the end of that parking lot.
I guess you could complain about the quality of the turf teepads... there was one that was a bit bumpy... but it really wasn't bad.
Would be nice to have a putting basket.
Really stretching for negatives. This was a beautiful, fun, challenging course and I don't have much bad to say about it.
Other Thoughts:
If you're playing in the morning, it might be worth bringing waterproof shoes or a change of socks. After searching up and down the hill on hole 2 for my disc, my feet were soaked in morning dew.
The course is pretty physically demanding. Be prepared for a hike.
After hole 11, go up the hill to throw down at 12. You might be tempted to go to the first visible teepad, but it's actually 13.
