The Haven Amphitheatre is a natural outdoor performance venue at the corner of The Barricade and The Scarp in Castlecrag. Willoughby City Council offers it for performing arts, rehearsals and selected social functions and directs first-time hirers to its festivals and events team. The site is set into a bushland landscape rather than a conventional indoor auditorium. Its current licensed spectator maximum, power supply and accessible audience routes were not established on the public listing and should be confirmed with council before advertising ticketed events.
