tried to do backpacking in 2 days with friends in October. The trail was very slippery right after snow and we didn't make it through. But the views are spectacular, and will try it this year again...

Popularly rated as one of the most spectacular hikes in America, this circuit is perfect for backpacking. A friend and I attempted to do this as a 2 day (1 night) backpacker, but due to inclement weather got pushed to a 2 night (slightly over 48 hr) finish. Thunderstorms at 12000+ ft are not to be trifled with. Picture perfect from start to finish, this loop features ever wildly changing scenery to keep even hikers with the shortest of attention spans interested.
