This is a great three hour hike, longer if you take breaks as we did. Gorgeous waterfalls and varied climbs. Definitely wear hiking shoes not sneakers as the paths vary in difficulty. It's described as intermediate and that's fair. The altitude gets you if you're not used to it so take it slow. The view at the top is really worth it and there are wonderful photo ops. We saw small kids wearing crocs and serious campers and lots of dogs. We didn't see much wildlife which was disappointing. One squirrel, two chipmunks and three birds! Wildflowers were still lovely in early September.
