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 project includes improvements along 63rd Street between Boulder and the intersection with Sunshine Canyon Drive. Construction is scheduled to begin in July 2026 with completion expected within 16 months.

Water quality monitoring at 18 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2026. The Community Justice Services publishes quarterly water quality reports on the Boulder County website.

How to Participate

Volunteers contributed over 6,312 hours to this program last year. The Community Justice Services coordinates with 16 nonprofit partner organizations throughout Boulder County to deliver services.

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