Summary

It's free to camp, with basic amenities: vault toilets, no water, no hookups. There are no designated fire rings or picnic tables, and fires may be restricted depending on conditions. RVs can access the site, but space is limited and primitive. Set along the Yellowstone River near Miles City, the area provides a quiet riverside setting ideal for fishing, boating, or wildlife viewing. Best visited in late spring through fall, it’s a peaceful, no-frills spot for self-sufficient campers seeking solitude and scenic river views.

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.
