Tongue River Reservoir Campground offers six separate camping areas with 156 total campsites (81 reservable) spread across scenic red shale and juniper canyon terrain in southeastern Montana.

The campground features two boat launch ramps with docks (at Campers Point and Pee Wee North), a marina store with fuel and supplies, dump stations, and fish cleaning stations to support both boating and fishing activities.

Most waterfront sites accommodate RVs up to 80 feet with electrical hookups available at select campgrounds, and reservations can be made up to 3-6 months in advance during peak season (mid-May through mid-September).
