Four Mile Canyon Creek Trailhead
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.
