People enjoy open space for physical, emotional and mental health. Remember to always be courteous. Don't forget to:
- Plan visits ahead of time and don’t park illegally at full trailhead areas.
- Remember to “keep the space in open space.” Maintain 6 feet of distance from people not in your household.
- Leave No Trace. Stay on trail and walk through mud. If you step off trail to let others pass, immediately step back on trail.
- Protect first responders. Know your limits and don’t take unnecessary risks.
- 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.

Parking - Know the Facts
It is unsafe and illegal to park in a way that:
- Blocks emergency access gate or fire lane
- Blocks pedestrian gate or driveway
- Prevents horse trailer parking
- Along any highway or a roadway where prohibited by sign
All vehicles parked in a manner described above are subject to being ticketed/towed.
Never park in the roadway.
The roadway is defined as the space between the white (fog) line and the yellow (center) line. If ANY part of your vehicle (tire, mirror) is between the white and yellow lines, your vehicle is a hazard and can be ticketed/towed immediately.
Because parking is very limited and our trailheads are quite popular, please show up early to get a parking spot.
Please keep your car doors locked and your car windows rolled up at all times while leaving your vehicle parked at OSMP trailheads. Also consider leaving important valuables at home or take them with you while visiting open space. To report suspicious activity please call City of Boulder Dispatch 303-441-3333 or Boulder County Dispatch 303-441-4444. For crimes in progress, call 911 immediately.

Learn about bringing your dog to OSMP. All dogs must be leashed in the Trailhead Leash Area. Beyond the trailhead, dog control requirements vary from trail to trail, so carefully watch for dog regulation signs at trailheads and trail intersections. On most OSMP trails in this area, dogs must be on a hand-held leash at all times unless they meet the voice and sight control standard and display a City of Boulder Voice and Sight tag. Dog excrement removal is required by law.
Horses are allowed on all trails. On-trail riding is encouraged to protect rare plants and wildlife habitat. Learn more about riding your horse on OSMP.
This trailhead is named for the large birds of prey that frequent the area and is a wonderful place to view our winter raptors -- bald and golden eagles and many kinds of hawks. Other wildlife includes prairie dogs, coyotes, foxes and snakes.
