Seasonal Raptor Closures to Begin on Friday, Feb. 1, on City Open Space
Raptor closures protect habitat for birds of prey to raise their young
The City of Boulder’s Open Space and Mountain Parks Department (OSMP) will institute seasonal wildlife closures on Friday, Feb. 1, to help protect habitats where birds of prey nest and raise their young. City open space is home to some of the highest-quality cliff-nesting habitat in the western United States. In 2018, this yearly wildlife-protection effort helped raptors nesting on OSMP to raise:
- Eight ospreys
- Seven peregrine falcons
- Seven prairie falcons
- Five golden eagles
- One bald eagle
While no designated trails will be closed, OSMP will close the following raptor habitat areas from Feb. 1 to July 31:
- Mount Sanitas Summit, accessible from the Mount Sanitas Trailhead a half mile west of Fourth Street and Forest Avenue.
- Third Flatiron, including the East and West Ironing Boards, Queen Anne’s Head and Jaws, and WC Pinnacle, accessible from the Chautauqua Trailhead.

These closures may affect access for climbers. The department encourages climbers to visit the department’s interactive map that shows climbing formations and whether they’re in wildlife closure areas.
OSMP and volunteers will conduct in-depth monitoring of raptor habitats, and closures may be lifted if monitoring indicates nesting attempts have failed or if raptors are not present. OSMP appreciates the support of visitors and our community in respecting these closures, which are patrolled by department rangers.
