Koutu Boulders

If you feel a game of bowls with balls up to 3 metres in diameter is just what you need, take a walk on the beach between Koutu and Kauwhare points on the south shore of the Hokianga Harbour where you will find the Koutu Boulders, one of the Hokianga’s better kept secrets.

The boulders are excellent examples of concretions : hardened nodules that form within sedimentary rocks. They are composed of the same material as the surrounding rock and they form when a cementing mineral binds grains of sediment into a cohesive mass. It has been estimated that the largest of the boulders may have taken 5 million years to grow.
