We made a left turn off of Route 139 onto FR 97 to access the southern entrance into Lava Beds National Monument and stopped in the forest for the night before going into the park. We found a quiet and pretty boondocking spot with widely spaced pines and an undergrowth of sagebrush. It’s just a few miles from the paved road but appears to get little use. We didn’t see any previously used spots so we just pulled off into a clearing. There are places large enough for any RV but you’ll have to make your own campsite plus there aren’t any established turn-around spots. It gets so little use that no one even drove down the road while we were camped.
