Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — December 2026

Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — December 2026

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 program is modeled after similar successful initiatives in Larimer County and Jefferson County. Boulder County’s version includes additional provisions for wildfire mitigation, affordable housing, and environmental sustainability.

Colorado state law requires all counties to provide these services to eligible residents. Boulder County exceeds minimum state requirements by offering expanded hours, multilingual support, and online access. In 2025, the county received a state award for excellence in service delivery.

Background

Volunteers contributed over 5,654 hours to this program last year. The Clerk & Recorder coordinates with 8 nonprofit partner organizations throughout Boulder County to deliver services.

The application deadline is July 16, 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 30 business days.
