Pirate Cave (Waiwaipuhi Sea Cave)

Enormous sea cave, 290 m long. It can be accessed only from the sea. Over the entrance falls a waterfall – thus every visitor gets a shower from it. During the winter, as the power of the waves increases, the entrance into the cave turns into a blowhole – the pressure of the air from the cave pushed back the waves, creating a fountain of mist and water.

Open Ceiling Cave

Collapsed sea cave – a circular sea basin that is connected to the sea with a large cave – natural arch that is some 13 m wide. Sea waves enter this cave. In the middle of this basin stands small island – remnants of the fallen cave ceiling.

Some 3 km long stretch of sea shore with numerous interesting geological formations in pahoehoe lava: natural arches, sinkholes and also several blowholes.
