Punalu'u Beach, The Big Island, Hawaii, USA.

This is "not your regular beach," according to Asquith. "This secluded stretch of sand is completely black," he said. "Caused by crushed volcanic rock particles and ash over millions of years, at first you may think the black sand looks ugly compared to traditional beaches, you will soon come to see the true and unique beauty of this beach, along with some pretty cool pictures for Instagram too!"
