Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Follow-Up Report

Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Follow-Up Report

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 Superior Senior Center offers related programming including free legal consultations, tax preparation assistance, health screenings, and social activities. Over 3,874 seniors participated in center programs last year.

A community information session will be held at the Superior library on Friday, May 15 at 6:00 PM. Translation services in Spanish and Nepali will be available. The session will also be livestreamed on the Boulder County YouTube channel.

Community Impact

The Board of County Commissioners will review progress on this initiative at their June 28 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $54,000, making it one of the largest collaborative efforts in the county’s history.

Background

The Rabbit Mountain open space property encompasses 2,272 acres and features 6 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

According to Robert Kim, director of Resource Conservation, this program served 62% more residents in 2026 compared to the previous year. “We’re seeing unprecedented demand from communities across Boulder County, particularly in Superior and the surrounding area,” Robert Kim said.
