Project Overview
City of Boulder Open Space and Mountain Parks (OSMP) plans to close the Marshall Mesa Trailhead for a year beginning in fall 2024 to conduct extensive trailhead improvements and support state coal mine mitigation work.
Most trails in the area will be open. However, visitors will not be able to access Marshall Mesa trails from the Colorado Department of Transportation parking lot at the intersection of Highway 93 and Marshall Road during this time.
State mitigation work in the Marshall Mesa area is expected to take four months to complete. OSMP trailhead renovations – focused on improving visitor safety and outdoor experiences in the area – are expected to take about eight months to finish.
