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.

The application deadline is July 12, 2026. Late applications will be accepted on a space-available basis. Incomplete applications will be returned with a list of missing items. Average review time is 29 business days.

Environmental review of the project area near Coal Creek Canyon Road found 7 sensitive species and 3 wetland areas requiring mitigation. The Area Agency on Aging worked with Colorado Parks and Wildlife to develop a habitat conservation plan.
