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.

The Board of County Commissioners will review progress on this initiative at their July 4 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

Water quality monitoring at 16 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2024. The Community Planning & Permitting publishes quarterly water quality reports on the Boulder County website.
