Whitianga: Cathedral Cove Thrilling Boat Tour, Caves & Snorkeling

At 7.8 metres, Cave Cruzer is the only vessel of its size in Mercury Bay, small enough to navigate inside caves and blowholes larger boats cannot enter, open-topped so nothing blocks your view above. Between stops, Brian opens the throttle.

You will cover 24 kilometres of protected Coromandel coastline at speed. Cave Cruzer goes inside the ancient blowholes and cave systems that line the route. Other boats do not.

Cathedral Cove is the centrepiece, Te Hoho Rock, the Sleeping Dragon, Narnia filming locations, seen from the water. Further along, Whale Cave and the hole in the rock at Poikeke Island are landmarks that only make sense from the water.

The tour heads inside Orua, New Zealand's second-largest sea cave, where Brian plays music so you can hear what 700 cubic metres of rock does to sound.

Optional snorkelling and rock jumping available, subject to conditions.
