Update: Boulder Canyon Trail Closure Due to Rockfall Mitigation Work (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.

Safety data from the Boulder area shows 16 reported incidents in the past 12 months, a 12% change from the previous year. The Sheriff’s Office has increased patrols along Nelson Road and added community outreach programs in response to resident feedback.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $471,000, making it one of the largest collaborative efforts in the county’s history.
