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.

South Boulder Creek Trail (1.5 mile between Baseline & South Boulder roads). ( 2.0 mile between South Boulder Rd & Marshall roads). This trail meanders southward along the riparian (stream side) corridor and is highlighted by self-guided interpretive displays. This area affords seasonal viewing of the bobolink, for which the trailhead was named, and other ground nesting birds. At South Boulder Road, the trail continues through an underpass then turns westward paralleling the road for approximately 0.2 miles before heading south along the creek once more. The trail meets Marshall Road at its southern end. Please note that dogs are not allowed south of the gate where the trail follows the stream south of South Boulder Road. This trail is sport chair accessible from the trailhead to the East Boulder Community Center turn off and south of South Boulder Road. North of the trailhead you may cross Baseline and via Gaptor Road connect to the Centennial Trail which is a hard surface trail.
This area is identified as being popular with people using wheelchairs. See the Accessible Trails Page for details.
