Boulder Canyon Trail Closure Due to Rockfall Mitigation Work Near Hygiene

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.

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

Data from the 2026 Boulder County Community Survey shows that 37% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 2,027 responses from residents across the county.

Background

Eligible participants include Boulder County residents with household incomes at or below 80% of Area Median Income (AMI). For a family of four, this is approximately $85,000 per year. Applications are processed on a first-come, first-served basis.

The Hall Ranch open space property encompasses 2,291 acres and features 11 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.
