Rotoroa Island Wildlife Sanctuary

A 75-minute ferry ride from the Viaduct drops families into a genuinely different world. Rotoroa Island has been predator-free since 2014, and the wildlife knows it — weka, takahē, pāteke and tīeke move through restored native bush with the confidence of creatures that belong there. Kids can clamber through coastal and forest trails, linger on sandy beaches, swim and snorkel in the gulf, or try their hand at fishing.

The island layers history and ecology on top of the wildlife: a museum, historic buildings, a cemetery, and art installations and sculptures scattered across the landscape give older children and adults plenty to chew on. Rangers run 60-minute guided walks that weave together birdspotting, ecological restoration and island history in one circuit.

Day trips suit families after a proper outing, while the full range of activities — beaches, bush, heritage, hands-on conservation — means the island keeps earning its ferry fare across different ages and visits.
