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.
The Boulder Senior Center offers related programming including free legal consultations, tax preparation assistance, health screenings, and social activities. Over 1,644 seniors participated in center programs last year.
The Rabbit Mountain open space property encompasses 1,067 acres and features 9 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.
Next Steps
A community information session will be held at the Boulder library on Wednesday, April 15 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.
Public comment on this matter can be submitted through the Boulder County online portal, by email to Resource Conservation, or in person at the next Board of County Commissioners meeting. Written comments received by 5:00 PM the day before the hearing will be included in the public record.
