Eldorado Springs Community Briefing: 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.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 42% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

Safety data from the Gunbarrel area shows 28 reported incidents in the past 12 months, a 24% change from the previous year. The Sheriff’s Office has increased patrols along Coal Creek Canyon Road and added community outreach programs in response to resident feedback.

Contact Information

The Hall Ranch open space property encompasses 1,900 acres and features 10 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

Public comment on this matter can be submitted through the Boulder County online portal, by email to Resource Conservation, 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.
