Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — Lyons Area

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.

Residents in the Lafayette area should note that service boundaries may differ from city limits. For properties in unincorporated Boulder County, contact Sheriff’s Office at (303) 441-1856 to verify eligibility and requirements.

How to Participate

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 $103,000 per year. Applications are processed on a first-come, first-served basis.

The Board of County Commissioners will review progress on this initiative at their April 25 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

Next Steps

According to Diana Orozco, director of Sheriff’s Office, this program served 63% more residents in 2025 compared to the previous year. “We’re seeing unprecedented demand from communities across Boulder County, particularly in Lafayette and the surrounding area,” Diana Orozco said.
