Getting there

What the agency says about the road in. For a long rig this is often the binding constraint — a site that fits is no use behind four miles of shelf road — and none of it appears in the campsite data.

Rigs not recommended on this roadRVs and trailers not recommended due to steep, rutted gravel access road.quoted from the driving directions
Unpaved approachThe campground is located one mile north of Warner Valley Ranger Station via gravel road and 17 miles north of Chester.quoted from the driving directions
