On the southern tip of the Big Island of Hawaii, Papakolea Beach is one of only four green sand beaches in the world. The sand gets its unique coloring from crystals created by the mineral olivine, which can be found in the surrounding volcanic rock — with the beach itself carved into a 49,000-year-old volcano.
