Rainbow Park Campground sits beside the Green River at the Rainbow Park Boat Ramp, serving as the head of Split Mountain Canyon and a popular launch point for river rafting trips.

The year-round campground offers four first-come, first-served tent sites ($12/night) with vault toilets and food storage, but no potable water or hookups; note that the 28-mile access road is rugged dirt and impassable when wet, requiring high-clearance vehicles.

The location provides excellent views of geologic features like the Mitten Park Fault and access to whitewater rafting, boating, and hiking within Dinosaur National Monument's 210,000+ acres.
