Colorado River Near Hot Sulfur | Overview
Flowing west from the high country of Grand County, the Colorado River near Hot Sulphur Springs offers anglers a classic Rocky Mountain experience. This section of river winds through open meadows and rugged canyons, showcasing some of the most scenic and productive water in the Fraser Valley region. As it passes through Byers Canyon, the river picks up character and energy—fast runs, pocket water, and plunge pools framed by dramatic red rock walls—before mellowing into wide, meandering stretches near town. The Hot Sulphur Springs State Wildlife Area provides excellent public access and a mix of water types for every angler. Whether you’re nymphing the deep runs, throwing streamers along undercut banks, or drifting dry flies through long glides, this reach consistently produces healthy populations of brown and rainbow trout. Its combination of easy access, scenic surroundings, and reliable fishing makes it one of the most popular sections of the upper Colorado River.

Recommended FLies
The Colorado River above the confluence with the Williams Fork is largely iced over for the season, and most sections are unfishable until spring. We’ll resume updates in late March or April as ice begins to come off. Through the winter, your best options are nearby tailwaters—including the Colorado River below Shadow Mountain, the Williams Fork, the Colorado River at Parshall, and Muddy Creek—which all offer more consistent open water and productive winter fishing.
