Fantastic trail! Had a bit of trouble finding it at first, but the trail itself was decently maintained, and the views were gorgeous. Once you get to a certain point (very near the top), though, the trail stops and if you want to reach the highest peak you have to make your own way, and if you're very careful can climb onto the highest bit of rock.
Came across one antelope on the trail which ran right across our path, and saw a load of tracks (possibly including elk?) though, besides birds and chipmunks, that's all our party of four saw.
Overall was super happy with the hike and would absolutely recommend it, just bring a lot of water and be prepared to stop for a few breaks along the way to catch your breath after long periods of uphill walking.
