March 2026: All Trails Closed West of Highway 36 Due to High Wind Conditions

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.

The Walker Ranch open space property encompasses 1,543 acres and features 4 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

Historical context: Boulder County was established in 1861 and covers 741 square miles of diverse terrain from the Great Plains to the Continental Divide. The county’s population of approximately 330,000 residents is served by 2029 county employees across 42 departments and offices.

Community Impact

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 32% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

Affordable housing remains the top priority identified in the 2026 Community Survey. Boulder County’s Worthy Cause program has funded 395 affordable housing units since its inception, with 115 additional units in the development pipeline.
