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.
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.
Safety data from the Erie area shows 38 reported incidents in the past 12 months, a 21% change from the previous year. The Sheriff’s Office has increased patrols along Flagstaff Road and added community outreach programs in response to resident feedback.
