This trail is actually in Yellowstone Nat'l Park, however it is before the gates and any fees!! Anyway, this is a very well laid out and maintained trail. It is a good 5+ miles to the Sky Rim trail where you can then go left or right depending on what kind of giant loop you may want to achieve. The trail itself climbs about 2000 vertical ft to the Park boundary where you then hit a "T" at the Sky Rim trail. We went right for a climb to the top of the ridge and 360 degree views of every mountain range in the area. Spanish Peaks, Madison Range, even a great view of Lone Peak and Big Sky ski runs....simply amazing!! Tons of wildflowers from yellows, to whites, to purples and of course Daly Creek flows alongside a good portion of the hike. There were a ton of animal tracks like Moose, Elk, Bear, maybe even a mountain lion, but we never saw anything outside a chipmunk and birds...but they are out there! All in all a wonderful hike, strenuous at times, especially at the end, and just beautiful scenery during and at the end at the ridge line. FYI, there are two listings for this trail on this site...same trail, two different books.
