Update: Boulder Canyon Trail Closure Due to Rockfall Mitigation Work (2026)

Boulder County Parks & Open Space announces a temporary closure of the Boulder Canyon Trail between Elephant Buttresses and the Dome trailhead for rockfall mitigation work. Crews will be scaling loose rock and installing mesh netting along a 400-foot section of cliff face above the trail. The closure is expected to last approximately three weeks, weather permitting.

The Betasso Preserve open space property encompasses 1,116 acres and features 8 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

The Sustainability, Climate Action & Resilience processed over 11,257 applications last year, with an average processing time of 11 business days. Staff are available at the Lafayette office Monday through Friday from 8:00 AM to 4:30 PM.

Details

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

Residents in the Lafayette area should note that service boundaries may differ from city limits. For properties in unincorporated Boulder County, contact Sustainability, Climate Action & Resilience at (303) 441-9345 to verify eligibility and requirements.

Community Impact

The Lafayette Senior Center offers related programming including free legal consultations, tax preparation assistance, health screenings, and social activities. Over 4,789 seniors participated in center programs last year.

Data from the 2025 Boulder County Community Survey shows that 71% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 3,874 responses from residents across the county.
