The black sand that forms the beach comes from volcanic rock, gradually pulverized over thousands of years by the incessant wave action at the shore. Much of the sand is actually very tiny pebbles, although higher up on the shore the pebbles give way to actual sand.

This beach is not very large and often has high surf, especially in winter. There are signs (permanently posted) warning of everything from man-o-war to being swept out to sea, and there are liferings positioned around the surrounding cliffs. Be very careful if you decide to venture into the water here.
