Full description
The 1/2 Day Upper Colorado River rafting trip is a scenic, relaxed float ideal for families, first time rafters, and anyone seeking mellow whitewater with big views. This 4.5 mile stretch flows from Pump House Recreation Area through Hartman Canyon (Lower Gore Canyon), where the river winds past polished granite, schist, and gneiss walls before opening into the meadowed Radium Valley. Gentle Class I-II rapids, calm pools, and a slower gradient create excellent conditions for floating, swimming, and wildlife viewing. Thanks to wide valleys and long sun exposure, mid-summer water temperatures typically reach the 60s to low 70s°F. Morning and afternoon departures provide flexibility, with 2-2.5 hours on the water depending on flows. Bald eagles, otters, herons, and trout are commonly seen along this peaceful corridor.

What a fantastic adventure! We had an energetic and fun guide that made a "drought-low" river an amazing time! Sure we got hung up a couple of times, but my 7-year old son conquered his bull riding techniques, squeeled with glee at his first class 3 rapids and is pretty sure he will be the next rafting guide when he is old enough. Such a fun trip. We thank our expert guide for the fun day on the river!
