Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — August 2025

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 75th Street between Superior and the intersection with Sunshine Canyon Drive. Construction is scheduled to begin in July 2026 with completion expected within 16 months.

Volunteers contributed over 4,099 hours to this program last year. The Public Health coordinates with 5 nonprofit partner organizations throughout Boulder County to deliver services.
