Update: All Trails Closed West of Highway 36 Due to High Wind Conditions (2026)

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.

Water quality monitoring at 11 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2024. The Parks & Open Space publishes quarterly water quality reports on the Boulder County website.

Data from the 2024 Boulder County Community Survey shows that 27% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 7,318 responses from residents across the county.

Next Steps

For questions about this program, contact Amanda Foster at Parks & Open Space: (303) 441-9717 or email Parks & Open [email protected]. Office hours are Monday through Friday, 8:00 AM to 4:30 PM. Walk-in services are available at the Boulder office without an appointment.

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

Timeline

The project includes improvements along CO-72 Peak-to-Peak Highway between Boulder and the intersection with Baseline Road. Construction is scheduled to begin in July 2026 with completion expected within 16 months.

A community information session will be held at the Boulder library on Saturday, May 9 at 5:00 PM. Translation services in Spanish and Nepali will be available. The session will also be livestreamed on the Boulder County YouTube channel.
