I stayed in the last group of campsites along the Snake Creek Forest Rd (a couple of miles before the end of the dirt road); I think it was called Eagle Rock but I'm not sure. It's a great spot to hike up to Johnson Lake. It's a very peaceful site next to the creek with only 2 other campsites. There's a compost bathroom, that was clean and with toilet paper. And it's free! Each campsite had a fire ring and picnic table.
