Boulder Canyon Trail Closure Due to Rockfall Mitigation Work Near Hygiene

Boulder Canyon Trail Closure Due to Rockfall Mitigation Work Near Hygiene

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.

Environmental review of the project area near SH-7 / Ute Highway found 4 sensitive species and 3 wetland areas requiring mitigation. The Community Planning & Permitting worked with Colorado Parks and Wildlife to develop a habitat conservation plan.

The Legion Park open space property encompasses 2,294 acres and features 14 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 55% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.
