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 approachThen turn east (left) to Utah highway 264 for .2 miles, then turn left (north) through the paved parking lot to the gravel road, then right (FS road 0124 downhill).quoted from the driving directions
