It's about a 6 miles drive in on a forest road. Nice gravel road and well maintained.
Dozens of spots to park your rig with tree cover along the main loop. Lots of small roads off of the main loop with more camp spots. Some of those roads were not accessible by our van, as they are a little rough.
The night we stayed it was just us and one small class C camper. Very peaceful, clean, and beautiful spot. Clean vault toilets available. No water so bring enough for your stay.
