Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Follow-Up Report

Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Follow-Up Report

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.

The Board of County Commissioners will review progress on this initiative at their May 28 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

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