Like the inside of a shell, the sounds of the sea and the air move through the drafty cave and create strange, hollow echoes in the natural corridors under the cliff. Water laps in from the opening, but a thick sediment has built up from higher tides, a haphazard barrier that helps to keep the waves in check.
