The boulders at Koutu Beach in Opononi are different and very interesting to see up close.
The boulders on the beach have been released from their soft host rock by erosion and simply rolled down and accumulated on the beach. Many people ask why are they spherical. The most likely explanation is that a small core rolled around on the sediment on the ocean floor and grew bigger much like a snowball does.
