September: 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 $146,000, making it one of the largest collaborative efforts in the county’s history.
Public comment on this matter can be submitted through the Boulder County online portal, by email to Clerk & Recorder, or in person at the next Board of County Commissioners meeting. Written comments received by 5:00 PM the day before the hearing will be included in the public record.
