Great hike. It's off trail for the majority of the time, so you'll need your topo map and compass, but once leaving the trail, my wife and I didn't see anyone the rest of the day. Gorgeous views of (South) Arapaho Peak. The Lake "Xanadu" (unmarked on maps) basin provided a nice little surprise on it's western shore, and the scree field to the summit was pretty stable. We went in early August, and there was just a small snowfield near the top that we had to cross for only about ~30'. Highly recommended. Get to 4th of July Trailhead early if you want to find parking.
