Pumphouse Recreation Site provides the most heavily used access point to 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 vault toilets and seasonal potable water (May-October).

Access to Class II-III whitewater, the Gore Canyon Whitewater Playpark, and hiking trails makes it ideal for both paddlers and anglers, though sites are close together and commercial rafting operations begin early in the day.
