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 featuring excellent pocket water and pullouts on the left side of the road.

Access is easy from roadside parking areas, though steep banks in some sections limit accessibility.

The site offers year-round fishing access to Boulder Creek with catch-and-release regulations (flies and lures only), and less crowding than town sections, especially during early morning and late evening hours.
