Campgrounds and RV parks near Otis, CO

Otis sits on Colorado's northeastern high plains in Washington County, roughly midway between Denver and the Nebraska line along US-34. RV travelers use the town as a quiet base for exploring the South Platte River corridor, prairie reservoirs, and the state wildlife areas that dot Logan and Washington counties. Interstate 76 runs a short drive north, connecting most of the region's campgrounds within an hour's travel. The closest overnight options range from primitive dispersed camping to full-hookup RV parks. Prewitt Reservoir State Wildlife Area sits in northeastern Colorado, with a shallow reservoir of roughly 2,431 acres ringed by riparian woodland, marshes, and prairie, and the South End provides shoreline camping. Buffalo Hills RV Park and Sterling RV Park offer developed sites with hookups closer to the town of Sterling. For a full-service state park experience, North Sterling State Park surrounds a nearly 3,000-acre high-plains reservoir north of Sterling, with Inlet Grove among its lakeside campgrounds. Tamarack Ranch State Wildlife Area, farther east along the South Platte, rounds out the options with primitive camping near I-76.

State park sites use the Colorado Parks and Wildlife reservation system. A reservation is required to camp at North Sterling State Park, and reservations can be made up to six months in advance online at cpwshop.com or by phone at 1-800-244-5613. Summer weekends at Inlet Grove and Elk Campground book out weeks ahead, so plan early for hookup sites. State wildlife areas run on a different model. No reservations are needed for camping at Prewitt Reservoir State Wildlife Area; it is a dispersed camping location where visitors find an available spot with a pre-existing fire ring and set up camp. Tamarack Ranch follows the same first-come approach for general camping. All SWA visitors need proper credentials. Anyone age 16 or older must have a valid hunting or fishing license, or a Colorado State Wildlife Area Pass, to access the property. Private options like Buffalo Hills RV Park and Sterling RV Park take direct reservations by phone or through their websites.
