This was a great hike if we had't gotten lost; not that it wasn't well marked, but be sure to read all reviews and everyone's notes before doing these hikes. We started at the wrong point - at the Overlook - and hooked up with the trail without a problem, but at about the 8 mile mark (yes we'd already gone off the trail at one point) we mistakenly took the fire trail and ended up 2 miles out of our way. However, if you stay on the trail, this is an excellent one as it is nice and clear, the falls are some of the prettiest in that you get SO close, and it was just overall a very pleasant hike. It is definitely a long downhill followed by a long uphill but they are gradual enough to not burn too badly. You do have to cross the river a few times and it was wet; I would allow about 6 hours for the hike.
