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.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $64,000, making it one of the largest collaborative efforts in the county’s history.

The Board of County Commissioners will review progress on this initiative at their May 13 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.
