Boulder Star area on Flagstaff Mountain is closed

The Boulder Star area on Flagstaff Mountain IS CLOSED to prevent gatherings amid the COVID-19 pandemic and because of ecological and safety concerns in the area. Visitors entering the Boulder Star closure area on Flagstaff Mountain can face up to a $1,000 fine or 90 days in jail. Learn more. Follow these other important recreation guidelines:

  • Stay home if you are sick or exhibiting COVID-19 symptoms.
  • Only recreate with members of your own household. 
  • Always bring a face covering. Wear it when you can’t maintain 6 feet of physical distance. 
  • Keep the space in open space! Always stay at least 6 feet from non-household visitors.
  • Visit OSMPTrails.org to see current trail closures, historical data that shows areas of high and low open space use and trails that are wider than 6 feet. See when trails are busiest through our Visitation Data Explorer.
  • Protect first responders. Know your limits and don’t take unnecessary risks.

Please - get muddy!

When trails are muddy or icy, please walk right through the mud without leaving the trail.
Off-trail detours to bypass muddy spots causes enormous damage to the trails and plants that grow alongside.

To report a problem on an OSMP trail, please make a service request through Inquire Boulder.
