The place we were actually headed for was called Hanauma bay. This crescent shaped beach, though stunningly beautiful in its’ own right, is particularly famous for the snorkelling on offer from the moment you step into the crystal clear waters. A coral reef stretches across the width of the bay, and lies in what was once the bottom of a volcano; the seaward rim of which was gradually worn away through thousands of years of waves beating upon the rock. The rest remains though and provides a visually dramatic protective barrier, with arms extended around the bay before slowly dipping to meet the sea.
