Boulder Canyon Trail Fishing Access Site provides multiple pullouts along Highway 119 between Boulder and Nederland, with the best fishing stretch at mile markers 35-37 offering terrific pocket water and pullouts on the left side of the road.

Access is easy from the highway, though steep banks in some sections limit accessibility; arrive early on weekends as popular spots fill quickly.

The site is subject to catch-and-release regulations with flies and lures only, and flows can spike dangerously with little warning from Moffat Tunnel releases, so check current conditions before visiting.
