Numerous formations in the Flatirons are closed to climbing every year from February 1 – July 31 to protect birds of prey. The closures have been in place for decades and have helped falcons, eagles, bats and other bird species reproduce and raise young without disruption and restore populations. The formations are monitored for nesting activity by OSMP staff and volunteers and closures dates may change. Trails can also be closed for construction and repairs, which may affect access to climbing formations.
