Temporary closures for peregrine falcon nesting in Acadia National Park
To provide peregrine falcons adequate space for nesting, the National Park Service temporarily closed areas including Jordan Cliffs Trail, Precipice Trail, and Valley Cove Trail in Acadia National Park until further notice starting March 1. In addition, the parking lot for the Precipice Trail will remain closed to vehicles until further notice. These annual closures protect the peregrine falcons from inadvertent human disturbance or harassment during the nesting period.
