COVID-19 ALERT

Always bring a face covering when you leave home and maintain 6 feet of distance

  • You will need a face covering to visit Boulder’s open space trails and parks. Always bring one with you when you leave home.
  • Place it over your nose and mouth when you can’t maintain 6 feet of distance from others.
  • Wear it around your neck or wrist when no one else is around.
  • Parents should help children older than 2 years old properly wear a face covering.
  • Help protect vulnerable community members and each other. 

Don’t forget: Keep the space in open space! Always stay at least 6 feet from others you don’t live with or haven’t agreed to have close contact with.

Please follow these other responsible recreation reminders:

  • 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. 
  • Plan ahead and consider recreating closer to home as parking is extremely limited - especially on Flagstaff Mountain.
  • Remember: Leave No Trace! Pick up trash and dog waste. Stay on trail and walk through mud. Step off if you need to maintain distance but quickly step back on trail.
  • For more responsible recreation reminders, please visit the Covid-19 Recovery page.
