Pros:
Great for beginners and hotel guests looking for some easy, fun recreation.
Confidence builder, expect aces if you're a DG guru.
Short 9-holes which can be completed in 15-30 minutes at a very quick pace.
Abundant ace opportunities.
$25 day use fee allows you access to the grounds at Mohonk Mountain House (which is worth it if you are looking to spend an entire day out!)
Hotel guests can play for free and receive complimentary discs if they are all returned at the end of the round. Discs are also for sale on the grounds.
It's DG, so it's fun and they are looking to expand 9 more holes, which would be sweet.
Brand new Disc Catcher baskets, easily identifiable from most tee pads.
People are really nice and friendly at Mohonk (keep in mind that this place is like a resort...)
Cons:
Not recommended for the seasoned DG-goer (you will not be challenged)
$25 day use fee for grounds use (which doesn't necessarily include use of the DG course which is reserved for guests of the Mohonk Mountatin House. Don't let this discourage you from "stumbling upon" it like I did and sneak a few rounds in).
Aside from the difficulty, this course reminderd me of Hyzer Creek (ya know, chopped down trees everywhere and no "natural flow" as seen in better area spots such as J-Park).
No par on placard? I assume they are all Par 3's and if so every hole is birdieable for even beginners.
Treacherous landscape...lots of cut down trees and rocks everywhere so watch your step. It's pretty much set on a hill side (think up and down) and wear your hiking boots.
Layout is not great or impressive by any means.
Never meant to be a public course.
Other Thoughts:
Try this spot if you want to site see at the Mohonk Mountain House and their grounds. However, if you are a diehard DG player, don't go out of your way to experiment this course at it's current state (you will be disappointed with the course, but nevertheless certainly = taken away by the beauty of the Mohonk Mountain House and all of its amenities).
