November 2025: 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.

Data from the 2026 Boulder County Community Survey shows that 86% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 2,882 responses from residents across the county.

Funding of $199,000 for this initiative comes from a combination of federal grants, state matching funds, and the Boulder County General Fund. The Board of County Commissioners approved the allocation during the 2026 budget session.
