COVID-19 Alerts

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.

HISTORIC INFO

Settlers' Park got its name because it was thought to be the location of the first permanent camp of American settlers in the Boulder area. The group pitched their tents at the base of the sheltering Red Rocks on Oct. 17, 1858.  A group of about 24 men heading toward Cherry Creek-Auraria gold strikes broke away from their wagon train because one of their members, Captain Thomas Aikins, thought that the "mountain looked right for gold" in the foothills west of the Boulder area. Red Rocks was purchased in 1920 and 1926.
