Boulder Canyon Trail Closure Due to Rockfall Mitigation Work Near Louisville

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 Lyons Senior Center offers related programming including free legal consultations, tax preparation assistance, health screenings, and social activities. Over 3,729 seniors participated in center programs last year.

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.
