One day trip we did on the West Coast is to drive an hour south of Westport to the village of Punakaiki. The drive down required a lot of concentration as the west coast road was very windy (aren’t they all?) but despite the bleak weather, I think it was worth the drive to see Pancake Rocks.
The rocks were quite unique in that the do look like pancakes. There’s of course a scientific explanation to all of this, and like most things geological it’s not the work of an instant.
