Arcadia is perfectly situated in the smallest of the four main bays on Magnetic Island, and is surrounded by the prominent Alma Bay and Geoffrey Bay.
Geoffrey Bay is a Marine National Park Zone - which means no fishing or collecting - but is great for exploring during low tide. The old barge jetty is a great spot for feeding rock wallabies at dusk.
Alma Bay is a very popular swimming spot for local and visitors alike. The Arcadian Life Saving Club patrols the beach on weekends and public holidays. Public amenities include a gas barbecue, picnic tables, shaded children's playground, changing areas and toilets.
Alma Bay is famous for its ANZAC Day Commemorations. Real-life soldiers from the Thirty-Fifth Field Squadron (Reservist Engineers) annually re-enact the events that took place and make a dawn landing right on the beach.
