92 campgrounds that take vehicles of 40 feet or more in Idaho

Boise National Forest holds the most of them in the state. The Forest Service runs most of them. Powell Campground takes the longest rig in Idaho at 200 feet.

A campground is listed when the longest permitted vehicle in its Recreation.gov site records is 40 feet or more. The figure is the longest single site, so most sites at a listed campground are shorter.
