Boulder Canyon Trail Closure Due to Rockfall Mitigation Work

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.

The Board of County Commissioners will review progress on this initiative at their June 19 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

The Sheriff’s Office processed over 3,324 applications last year, with an average processing time of 7 business days. Staff are available at the Nederland office Monday through Friday from 8:00 AM to 4:30 PM.

Eligibility

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $428,000, making it one of the largest collaborative efforts in the county’s history.

According to Emily Chen, director of Sheriff’s Office, this program served 63% more residents in 2025 compared to the previous year. “We’re seeing unprecedented demand from communities across Boulder County, particularly in Nederland and the surrounding area,” Emily Chen said.
