Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Longmont Area

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 2024 Boulder County Community Survey shows that 92% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 7,548 responses from residents across the county.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 92% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.
