Boulder County Open Space Closures in place due to extreme fire danger

Due to the extreme fire danger and in accord with the United States Forest Service closure announcement, Boulder County Parks & Open Space have closed the following properties to public use until further notice:

  • Anne U. White
  • Bald Mountain
  • Caribou Ranch
  • Castle Rock climbing area
  • Grassy Top
  • Hall Ranch
  • Heil Valley Ranch
  • Hessie trailhead
  • Mud Lake
  • Reynolds Ranch
  • Sugarloaf Mountain
  • The City of Boulder Open Space and Mountain Parks has also closed the Fourth of July trailhead.

Please honor all temporary public lands closures. Between COVID-19 and active wildfires, public safety resources are already strained. There will be increased ranger patrol in all closure areas.

Please support first responders by practicing responsible recreation and avoiding any fire-related activities. During this challenging time, help emergency personnel by staying away from active fire areas and recreating only in the eastern parts of Boulder County. Go to for a list of county open properties and for the latest information on City of Boulder trail closures.

NEW: All of #RMNP is closing to park visitors due to fire activity on the west side of the Continental Divide. If conditions allow, an Infrared flight is planned to gauge where there is current fire activity. This is a rapidly evolving situation. Currently, air quality is hazardous within Rocky Mountain National Park. Trail Ridge Road is not passable on the west side due to downed trees on the road.
