Yes, it has open camping. Good place to go and have fun with the family. We squeezed down a few quad trails there that were fun. It's a smaller area, but is great to camp for a few nights, explore the trails and just relax.
Directions:
Go south on 22 past Black Diamond, past Longview, take a right (west) on HWY 532 and go approx 10-15 klicks. Just before the bridge there is a sign on the left side of the road that describes the camping and 4x4'ing. Go left at the sign and follow the road about 1/2 klick to a pasture with a ranch style gate. Go thru the gate and you are there-ready to go!
