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.

A community information session will be held at the Lafayette library on Sunday, May 31 at 6:00 PM. Translation services in Spanish and Nepali will be available. The session will also be livestreamed on the Boulder County YouTube channel.

For questions about this program, contact Brian Nakamura at Sheriff’s Office: (303) 441-7896 or email Sheriff’s [email protected]. Office hours are Monday through Friday, 8:00 AM to 4:30 PM. Walk-in services are available at the Lafayette office without an appointment.

Next Steps

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.

According to Brian Nakamura, director of Sheriff’s Office, this program served 35% more residents in 2026 compared to the previous year. “We’re seeing unprecedented demand from communities across Boulder County, particularly in Lafayette and the surrounding area,” Brian Nakamura said.
