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 project includes improvements along Foothills Highway between Erie and the intersection with CO-72 Peak-to-Peak Highway. Construction is scheduled to begin in September 2026 with completion expected within 13 months.
