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

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.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 39% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

Water quality monitoring at 11 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2025. The Parks & Open Space publishes quarterly water quality reports on the Boulder County website.
