Fall seems like the perfect time of year for this hike. Low enough elevation it did not get too cold & the colors are amazing. It is a nice hike for a weekend to get away, and good for beginners. It is mainly traveled by horse packers, though we saw no one on our adventure. There are some beautiful big trees and beautiful vistas.
Be warned the trail is not well marked, make sure to have a map, preferably a topo. Being in the Wilderness area fires are permited year round, with a permit from the ranger station which is closed weekends in the late fall. It is also possible to take dogs. There was water in Fish Creek, we (myself and the ranger station) weren't sure if there would be this time of year.
Over all we had a wonderful trip, the only negative being the unmarked trail at times.
