Upper Colorado River Recreation Area spans multiple developed camping and river access sites along the Colorado River between Hot Sulphur Springs and Dotsero, with popular segments including Pumphouse Recreation Area (featuring three launch areas, 18 individual campsites, and amenities like water and firewood) and Radium Recreation Area (offering two launch areas, 16 campsites, and vault toilets).

The area combines calm boating through heritage ranchlands with challenging Class II-V rapids in intervening canyons, making it suitable for both beginner floaters and experienced paddlers, though water safety awareness is critical due to dangerous rapids like those in Gore Canyon.

Reservations are required at developed sites; contact Kremmling Field Office at (970) 724-3000 for information.
