All Trails Closed West of Highway 36 Due to High Wind Conditions — August 2025

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.

For questions about this program, contact Maria Gonzalez at Clerk & Recorder: (303) 441-2987 or email Clerk & [email protected]. Office hours are Monday through Friday, 8:00 AM to 4:30 PM. Walk-in services are available at the Lyons office without an appointment.

Water quality monitoring at 16 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2024. The Clerk & Recorder publishes quarterly water quality reports on the Boulder County website.

Timeline

Transportation access remains a key concern. Boulder County’s Via mobility program provides door-to-door transit service for residents in Lyons and surrounding communities who cannot access fixed-route bus service. RTD routes B, J, and BOLT serve major corridors.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 31% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

Eligibility

The program is modeled after similar successful initiatives in Larimer County and Jefferson County. Boulder County’s version includes additional provisions for wildfire mitigation, affordable housing, and environmental sustainability.
