Boulder Canyon Trail Closure Due to Rockfall Mitigation Work — April 2024

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.

Data from the 2026 Boulder County Community Survey shows that 30% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 6,751 responses from residents across the county.

Water quality monitoring at 10 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2026. The Community Justice Services publishes quarterly water quality reports on the Boulder County website.
