Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — April 2024

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 24, 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 20 business days.

Volunteers contributed over 3,699 hours to this program last year. The Community Planning & Permitting coordinates with 10 nonprofit partner organizations throughout Boulder County to deliver services.

The project includes improvements along Foothills Highway between Superior and the intersection with SH-7 / Ute Highway. Construction is scheduled to begin in June 2026 with completion expected within 18 months.
