Granite and limestone cliffs here were hollowed out by the sea to form caves. "The Woolshed" is a large cavern carved into the cliff, and there are steps down to the cliff base. Or check out "The Tub," a large, craterlike hole in the cliff around 30m (98 ft.) deep and 50m (164 ft.) wide. Look out for the tree-trunk ladder and climb down into the crater to walk into the mouth of the cave. Don't get too close to the edge, however; a slip into the swirling surf would be fatal.
