On my journey to Frost Valley my GPS decided that the course is 6 miles short of where it actually is, it took me up one of the craziest back mountain roads or long skinny gravel driveways I've ever been on, and eventually figured there is no way this could be right and turned around which is was scary enough and put the vehicle in low gear and foot on brake back down all the way. Had no cell phone service, so I headed back to the last "town" and found a runner, and asked where the ymca was, and it's obvious after crossing the bridge to continue on the paved road(ignoring GPS) and then you will see signs to it.
After finally getting to the course destination, the joyous journey had only yet just begun. Had I known before hand what I was about to embark on - I probably would not have decided to bring my video camera/tripod with me. I played the Blue course and holy crap this course is massive! I physically paid the price toting extra equipment around and having to probably double my total hiking to capture this video footage, although I think it was worth it in retrospect. I'd do a hole by hole breakdown, but I think the video says enough although it doesn't do the elevation justice.

Highlights(too many really):
As I walked down the fairway of the signature par 5 - hole 5 to scope out where the basket was, I nearly crapped my pants because I got the butterflies and adrenaline pumping about to play this beauty - probably well over 100' of elevation downhill from the top of the mountain with 2 different fairways and cliffs to the sides and the basket 933' away down the tunnel of pines and then hardwoods with huge boulders protecting the raised green with a pit in front of it. When I finished hole 5 I got temporally confused when I saw the #5 on the basket because I thought I had played at least 9 holes already or felt like it physically at least.
The death approach and putt to the long basket on hole 12 will get your heart racing, it's quite steep and tight and then on top of that has a cliff behind it!
Hole 16 is another picturesque signature hole, this pretty par 4 is framed out with hardwood trees to the sides, you tee from the mountain top cliff to the basket straight ahead downhill with the backdrop view of the neighboring mountain top. Probably well over 100' of elevation drop and 784' long. If your approach shot goes 40' or so long you risk going down the cliff behind the basket.
In conclusion, out of the 150+ courses I've played, Frost Valley is a destination course easily worthy of best of the best rating. The Catskills are quickly becoming the premier disc golf region although it's spread out a bit from Warwick to Mine Kill and J-park to Stoney Kill. If you live or stay near Kingston NY you are about equidistant to some of the best disc golf you will find anywhere. I'd recommend playing Frost Valley last though on a road trip since everything else will seem blander afterward. It would be like having Charlotte McKinney as your first girlfriend. I played Walnut Mountain in the morning before Frost Valley which is a good pairing as it's currently a quick fun more open than wooded 9 holer, although it could be epic as well expanding to 18. Mine Kill is another option to pair with the same day although both in the same day would be equally epic and tough and you could easily want to spend the entire day at either course, they do compliment each other very well with MK providing more open style course while FV is heavily wooded. **Update** I returned to FV for the NY State DG Championships and stayed at the lodge for 3 nights. I had an absolute blast taking in the surrounding wildlife, the camp fires, and the stars! The rooms in the Castle were really nice compared to the lodge and there are other housing options available and cabins, so staying at the YMCA is totally worth it IMO especially with everything that have facility wise at your disposal and getting 3 meals/day included. So I've played the Blue course 5+ times and the Red course once. I still haven't explored all the different routes on the Blue course from the tees. The Red course is not as easy as I thought and had some real tricky holes, like 8 and 9, but there are a number of ace runs. If you have a bucket list or only have time for one course to play though Frost Valley would absolutely be the ONE!
