Within Keyhole Reservoir State Park, Tatanka Campground provides electric hookups and water access for RVs up to 40 feet. The Wyoming Department of Parks and Cultural Resources manages this established campground, where most sites include water and electric connections. A dump station operates at the entrance, and concrete picnic tables anchor each site alongside fire rings.
Sites spread across slightly sloped terrain with adequate spacing between neighbors. Several campers note the uneven ground requires leveling, though most RVs manage without difficulty. The campground maintains multiple bathroom facilities throughout, though the central shower house may require a walk from distant sites. During weekdays, the area stays relatively quiet according to multiple reviews.
Keyhole Reservoir sits within walking distance, offering fishing opportunities and space for paddleboarding. "Close walk to lake shore to play, fish or paddle board," notes Kristen + Billy P.. Pat's Point features a trail where visitors can watch sunsets over the water. The reservoir supports walleye fishing and various water sports, though sandy beach areas remain limited.
Reservations are available online, and the campground accommodates both tent and RV camping. For a different lakeside experience, Pronghorn Campground — Keyhole State Park offers an alternative just northwest of Tatanka.
