Sawhill Ponds 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.

Ice on ponds and lakes
You can help to keep you and your pets safe by keeping them off OSMP's icy lakes. Many times, pets that fall into icy waters will be able to get out or self-rescue without assistance.
If it happens to you while visiting OSMP and your pet is unable to get out of the water, stay off the ice! Call 911 and Boulder Fire-Rescue will respond and rescue your pet!

No kayaks, carry-on boats, watercraft, inner tubes, or wadding and swimming are permitted.

Sawhill Ponds is the home to many different kinds of waterfowl, fish, birds of prey, amphibians and reptiles. During spring and fall, the ponds provide a stop-over for migrating ducks.
The 18 ponds at Sawhill are the result of a gravel mining operation and reclamation project. Boulder Creek, now at the northwestern boundary of the ponds, has traversed the entire area in the geologic past. This ancient floodplain laid down great quantities of sand and gravel, and these deposits were mined for several decades until the early 1970s. When the mining ceased, groundwater filled the pits resulting in a wetland area that provides marvelous habitat for many species of wildlife. The ponds are stocked by Colorado Parks & Wildlife, and warm water fishing is a popular activity.
