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 a boat slide with steps at Ramp #2) and ample parking for trailers.

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

Direct river access provides opportunities for wade fishing and paddling ranging from calm flat water to Class III rapids, with the Gore Canyon Whitewater Playpark featuring a manmade wave popular with kayakers just above Boat Ramp #2.
