The City of Boulder will reopen limited trail access in the Marshall Mesa area on Friday, Feb. 18, after assessing and fixing trail damage sustained during the Marshall Fire.

City of Boulder Open Space and Mountain Parks (OSMP) will open the following trails on Friday for on-trail access only, which will enable visitors to complete a “loop” experience on trails managed by OSMP and Boulder County Parks & Open Space:

  • Greenbelt Plateau Trailhead
  • Coalton Trail
  • Greenbelt Plateau Trail
  • Greenbelt Plateau connector
  • High Plains Trail
  • Community Ditch Trail
  • Cowdrey Draw
  • Marshall Valley Trail section that connects to Marshall Road

On-trail-use-only regulations will be enforced as the area has changed since the Marshall Fire and hazards may be present. Visitors can park at the Greenbelt Plateau and Flatirons Vista trailheads to access reopened trails, but they should exercise extreme caution when walking along or crossing Highway 93 or Marshall Road.

An extended closure of the Marshall Mesa Trailhead and the Marshall Mesa, Marshall Valley and Coal Seam trails will remain in place because of damage sustained during the recent fire. OSMP highly encourages visitors to text “OSMP” to 888-777 for text alerts that will inform them of Marshall Mesa-area trail closures the department institutes to limit damage to trail tread and adjacent vegetation when muddy trail conditions exist.
