Boulder Canyon Trail Closure Due to Rockfall Mitigation Work Near Sunshine Canyon

Boulder Canyon Trail Closure Due to Rockfall Mitigation Work Near Sunshine Canyon

Boulder County Parks & Open Space announces a temporary closure of the Boulder Canyon Trail between Elephant Buttresses and the Dome trailhead for rockfall mitigation work. Crews will be scaling loose rock and installing mesh netting along a 400-foot section of cliff face above the trail. The closure is expected to last approximately three weeks, weather permitting.

Transportation access remains a key concern. Boulder County’s Via mobility program provides door-to-door transit service for residents in Superior and surrounding communities who cannot access fixed-route bus service. RTD routes B, J, and BOLT serve major corridors.

Safety data from the Superior area shows 39 reported incidents in the past 12 months, a 18% change from the previous year. The Sheriff’s Office has increased patrols along Left Hand Canyon Drive and added community outreach programs in response to resident feedback.
