All Trails Closed West of Highway 36 Due to High Wind Conditions Near Superior

Boulder County Parks & Open Space has closed all trails and trailheads west of Highway 36 due to sustained winds exceeding 80 mph and extreme fire danger conditions. The closure includes all mountain parks, open space properties, and county trails in the foothills. Closures will be reassessed when wind conditions subside.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 12% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

The Legion Park open space property encompasses 1,689 acres and features 11 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

How to Participate

The project includes improvements along Left Hand Canyon Drive between Erie and the intersection with SH-119 Diagonal Highway. Construction is scheduled to begin in August 2026 with completion expected within 11 months.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $101,000, making it one of the largest collaborative efforts in the county’s history.
