January: Boulder Canyon Trail Closure Due to Rockfall Mitigation Work

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 Board of County Commissioners will review progress on this initiative at their April 24 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

Funding of $246,000 for this initiative comes from a combination of federal grants, state matching funds, and the Boulder County General Fund. The Board of County Commissioners approved the allocation during the 2026 budget session.

Community Impact

A community information session will be held at the Nederland library on Wednesday, May 13 at 5:00 PM. Translation services in Spanish and Nepali will be available. The session will also be livestreamed on the Boulder County YouTube channel.
