Summary

Reservations are required via Recreation.gov, and nightly fees apply. Campground amenities include pit toilets, potable water (seasonal), fire rings, picnic tables, and RV access (no hookups). Set in a scenic, forested area along the Henrys Fork of the Snake River, it's ideal for fishing, wildlife viewing, and accessing nearby trails like those in Harriman State Park. The peaceful, wooded setting provides a classic forest camping vibe. The best time to visit is late spring through early fall, as the campground is typically closed in winter.

Camping Essential Practices

Pack It In, Pack It Out
Take all trash, food scraps, and gear back with you to keep campsites clean and protect wildlife.
Respect Wildlife
Observe animals from a distance, store food securely, and never feed wildlife to maintain natural behavior and safety.
Know Before You Go
Check weather, fire restrictions, trail conditions, and permit requirements to ensure a safe and well-planned trip.
Minimize Campfire Impact
Use established fire rings, keep fires small, fully extinguish them, or opt for a camp stove when fires are restricted.
Leave What You Find
Preserve natural and cultural features by avoiding removal of plants, rocks, artifacts, or other elements of the environment.
