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.

Unpaved approachBe advised- FS road 327 is a dirt road that is only graded a couple of times a year.quoted from the driving directions
