Update: Boulder Canyon Trail Closure Due to Rockfall Mitigation Work (2025)

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.

A community information session will be held at the Lyons library on Saturday, June 6 at 7:00 PM. Translation services in Spanish and Nepali will be available. The session will also be livestreamed on the Boulder County YouTube channel.

The program is modeled after similar successful initiatives in Larimer County and Jefferson County. Boulder County’s version includes additional provisions for wildfire mitigation, affordable housing, and environmental sustainability.

The application deadline is May 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.

The Lyons Senior Center offers related programming including free legal consultations, tax preparation assistance, health screenings, and social activities. Over 3,400 seniors participated in center programs last year.

Next Steps

Wildfire risk mapping conducted by Wildfire Partners shows that 39% of properties in the Lyons area are within the wildland-urban interface. Free home assessments are available through the Wildfire Partners program, with rebates of up to $2,500 for mitigation improvements.

Funding of $195,000 for this initiative comes from a combination of federal grants, state matching funds, and the Boulder County General Fund. The Board of County Commissioners approved the allocation during the 2026 budget session.
