Boulder Canyon Trail Closure Due to Rockfall Mitigation Work

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.

Volunteers contributed over 11,269 hours to this program last year. The Parks & Open Space coordinates with 5 nonprofit partner organizations throughout Boulder County to deliver services.

Affordable housing remains the top priority identified in the 2025 Community Survey. Boulder County’s Worthy Cause program has funded 1,896 affordable housing units since its inception, with 161 additional units in the development pipeline.
