Reviews

Selected reviews

Verbatim from guest reviews on Recreation.gov ↗ (8 reviews, ★ 4.0). Not written or edited by us.

“This is a great group campground, although remember that it only has vault toilets, no running nor potable water. You might want to bring some toilet paper in case they run out.”

Lee T 5 · Jun 2025 · Recreation.gov

“THE CAMPGROUND DOES NOT EXIST IT IS A ROAD END WITH FALLEN TREES. Horrible”

Ines M 1 · Aug 2023 · Recreation.gov

“The location was great, however, getting out of the campsite- around the curve near the bathroom was a bit challenging with our 32 ft trailer. Otherwise, we loved the location.”
