Absolutely beautiful area. Plenty of campsites around the small lake that are right up next to the water, but to get the good spots, It's first come first serve. The water is pretty cold and crystal clear when we were up there at the beginning of June. 

Things to expect:

You're about two hours away from any cell service. 

The road to get up is all rocks and off-road going up a mountain. 4x4 with traction tires is a must. Kit up. Have a satellite phone, and expect to drive through snow up there at the beginning of June.
