Pros:
A brushy course on top of a high plateau.
A short drive up a road alongside I-70 in Edwards, you come to a gently sloped plateau overlooking the interstate with great views of the Sawatch Range. You can see a long way, as the track of land doesn't have any bushes taller than 12 feet. It's quite secluded, as there isn't really much else at the end of the dirt road.
Scattered throughout, plainly in sight, are nine numbered DGA baskets. In between the size and the shrubbery, you can spot several at once. Brightly colored rocks mark natural tees.
The holes themselves are all attackable by rec-level players. With virtually no obstacles, all it takes is a nice drive, no longer than 300', to have a birdie. This gives it a certain fun factor--who doesn't enjoy feeling like a birdie machine while enjoying great views?
There is a certain amount of elevation as well, playing both up and down. A couple of basket have steep drop-offs nearby, which requires extra finesse.
It's also a very quick play.
Cons:
CONS Probably the biggest con is lack of challenge and interest. It's wide open other than a few short, bushy trees, and most holes are under 300 feet. Many experienced players will be disappointed not to shoot more than half birdies.
Getting there can be a bit of an issue. The dirt road requires high clearance. I parked on the side of the road about a quarter mile away and walked, but I'm not entirely sure that's a good plan.
The lack of amenities is noticeable. With no tee signs or concrete, it's pretty hard to tell where to walk to next. Furthermore, with several baskets visible at all times, knowing which to throw to isn't clear, even with UDisc's GPS.
The steep drop-offs behind a couple of baskets are truly steep. I overthrew one basket and ended up almost all the way to the main road below. Honestly, it was foolish to slide down the hill to fetch the disc, and I'm lucky I could scramble back up without rolling an ankle.
Last, the wind up here can be bad. On a plateau, any afternoon turbulence can be felt in full. When I played, it was consistently 20+ MPH. On the bright side, that's an extra challenge.
Other Thoughts:
Like most courses where you can see every basket from the middle of the course, Singletree lacks challenge. The views are a consolation, and it has clear tee indications and good baskets, so it's Passable. But you can also feel free to pass by.
