Pros:
An extremely solid course with lots of lines and gorgeous views.
-Amenities: Solid, if not top-notch. Mixed baskets (all fine), tee signs of slight usefulness, concrete pads, next tee cues.
-Layout: The original 18, followed by an additional 9-hole loop. It's pretty easy to stop after the first set.
-Beauty: The course itself is scrubby, but the backdrop is gorgeous mountains. Frisco is at the base of a couple of peaks, and they loom throughout the round. Parts of the course also have great vistas of the Dillon Reservoir.
-Challenge: Actually moderately difficult, despite all the par-3s. The trees catch anything that come near them, requiring very specific lines and creating some very hard scrambles. I'd pin it as upper-level Intermediate in parts, with some easier stretches as well.
-Shot Shaping/Gameplay: A lot of quirkily demanding shots with punishing scrub. Curves are important, and many shots throw blind around firs to the pin. Shapes range from subtle to steep, as do the inclines - several holes have very steep drops, while others are totally flat. Added in are some easy wide open holes to get you back to even when you bogey. A couple of par-4s, but the rule is longish par-3s. Having a good straddle putt, and long legs to lean out of trees, will be valuable assets. The final nine increase the density a bit more, requiring more laser lines and less lollipop shots.
-Multi-Pins: Several rotating pin placements per hole, with indicator system.
Cons:
-Par-3 Golf: It gets a little old after a while. The creativity of shapes is impressive, but Peak One would be much better for the inclusion of multi-shot strategic holes.
-Blind Pins and Shots: Big downside for first-timers. A large number of pins are blind, which isn't good when the tee signs are as vague as these are. Further, throwing so many blind shots into dense trees is a recipe for lost discs, especially if you get caught up in something above the ground. At any rate, a lot more searching than desirable.
-Scrambling: Sometimes just not fun. If you're in the middle of a fir, you can't throw more than 10 feet.
-Navigation: At times, confusing. You can get turned around the wrong way, and the dirt makes it difficult to wear in any obvious trails.
-Dusty: A normal desert con, but especially bad here. Some of the grittiest, disc-dirtying rounds I've played.
Other Thoughts:
Peak One is a course that I enjoyed like a Good course, but in an honest evaluation has the variety to earn it a Very Good rating. There is lots of shaping with very real punishments for flubs, combined with occasional elevation and some stunning scenery. There are navigation and pin-finding issues, but I tend to de-emphasize these. Play with a local if you can, and you're likely to have a great round.
