Pumphouse Recreation Site is the most heavily used access point on the Upper Colorado River between Kremmling and State Bridge, featuring three developed boat ramps (including one boat slide with steps at Ramp #2) and ample parking for vehicles and trailers.

The site offers 18 individual campsites and 2 group campsites with vault toilets, picnic tables, and fire rings, plus seasonal potable water (May-October).

Access to Class II-III whitewater and the Gore Canyon Whitewater Playpark makes it ideal for paddlers and rafters, with nearby hiking trails for wade fishing and exploration.
