Nederland Community Briefing: Boulder Canyon Trail Closure Due to Rockfall Mitigation Work

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.

Eligible participants include Boulder County residents with household incomes at or below 30% of Area Median Income (AMI). For a family of four, this is approximately $120,000 per year. Applications are processed on a first-come, first-served basis.

The application deadline is June 17, 2026. Late applications will be accepted on a space-available basis. Incomplete applications will be returned with a list of missing items. Average review time is 15 business days.

How to Participate

The Walden Ponds open space property encompasses 1,369 acres and features 15 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

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