Update: Boulder Canyon Trail Closure Due to Rockfall Mitigation Work (2025)

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 May 4 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

The Gunbarrel Senior Center offers related programming including free legal consultations, tax preparation assistance, health screenings, and social activities. Over 1,570 seniors participated in center programs last year.

Details

A community information session will be held at the Gunbarrel library on Tuesday, May 26 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.

Transportation access remains a key concern. Boulder County’s Via mobility program provides door-to-door transit service for residents in Gunbarrel and surrounding communities who cannot access fixed-route bus service. RTD routes B, J, and BOLT serve major corridors.
