About Pumphouse Recreation Area

Overview

Managed by Kremmling Field Office

The Pumphouse Recreation Area is part of the Upper Colorado River Special Recreation Management Area (SRMA), providing opportunities for developed camping, river access and access to hiking trails. With over 100,000 annual visitors the sites facilities include 3 developed boat ramp sites, 12 vault toilets, day use and overnight parking, 18 Single Campsites and 2 Group Campsites. The campground has a seasonal potable water system that may be in operation between mid-April to mid-November (not available for trailer hookups or filling of Recreational Vehicle and Travel Trailer filling).

Recreation

Pumphouse Recreation Area is the most heavily used access point for the Upper Colorado River between Kremmling and State Bridge. Those floating downriver access calm flat water to Class III whitewater rapids.

The Gore Canyon Whitewater Playpark is located just above Boat Ramp #2 and provides a manmade wave that is popular for kayakers, stand up paddle boarders and other small watercraft. It is also an exciting splash feature for watercraft coming downriver from Boat Ramp #1.

Hiking opportunities accessed from the Pumphouse Recreation Area provide ample access for wade fishing and exploring along the Colorado River.

The Gore Canyon Trail is open to foot travel only providing access upriver for 1.5 miles. Keep an eye out for the historic retaining walls holding the trail in place that early surveyors of Gore Canyon and homesteaders developed to access this area of the river for finding a railroad route and efforts to divert water for irrigation.

The Gore Canyon Ranch Trail is open to foot travel only and provides access downriver for 1.25 miles connecting to the Gore Canyon Ranch Trailhead and Parking Area. This undeveloped area was the site of a homestead ranch and acquired by the BLM to improve and expand public recreation and access, provide educational opportunities on the area’s history, wildlife and responsible recreation opportunities and restore habitat for wildlife.

The historic Argentine Trail is open to foot travel only and is accessed from the Gore Canyon Ranch Trail. This trail is not for the lighthearted as it has steep drop offs as much of the trails was blasted into the cliffs of Hartman Canyon allowing access for surveyors and mule trains. Those floating down stream can see this trail high up the canyon wall on river left.

Facilities

Each campsite must be reserved through Recreation.gov and has varying space for parking (see parking size limitations for each campsite before completing your reservation), a picnic table, a fire ring, and close proximity to a vault toilet and trash receptacles. For campsites 1-8, driveway parking is 35 feet or less in length and is back-in/pull-in. Additional vehicles may park along the roadway adjacent to the campsite if space allows or must park in the general parking areas. Camping within vehicles outside of the assigned campsite driveway is not permitted. Campsites 9-18 are parallel parking and typically have space for two vehicles and small trailers. Additional vehicles must park in the campground overflow parking across from Group Campsite A.

Potable water may be available May - October. However, do not rely on this as the water source for your trip's needs as it is not always operational.

There are no electric hook-ups and cell service is non-existent without a booster.

There are three boat ramps with restrooms. Boat Ramp #2 adjacent to the Gore Canyon Whitewater Play Park is a boat slide with steps. Boat ramps have electricity.
