 Falcon chicks are often banded to study migration, habitat use, and longevity.Some trails may be closed in spring and early summer to avoid disturbance to falcon nesting areas.Recreational activities from spring through autumn include car and bus touring along the park's paved loop road; hiking, bicycling, and horseback riding on carriage roads (motor vehicles are prohibited); rock climbing; kayaking and canoeing on lakes and ponds; swimming at Sand Beach and Echo Lake; sea kayaking and guided boat tours on the ocean; and various ranger-led programs.
