Float a gentle stretch of the Upper Colorado through Gore Range foothills on a half-day trip from Kremmling. This family-friendly run mixes calm water, a few small rapids, swims and scenic pullouts between Pumphouse Recreation Area and Radium.
More ways to explore the area's outdoor wonders
You push off beneath high pines and the Gore Range rises like a stone wall to the west — the river at first a wide, slow ribbon, then a corridor that quickens over a scatter of riffles. The trip launches from AVA’s Kremmling Outpost; a short vehicle shuttle drops you at Pumphouse Recreation Area and, within minutes, the current is doing much of the work. Expect a mix of flatwater lounging and a handful of small, playful rapids that encourage splashes, swims and plenty of sunbathing.
