Hike or drive in the direction of the visible cinder cone known as Pu'u o Mahana. The surrounding area is rich in olivine, a greenish mineral that when extracted by the ocean's forceful waves, helps to create the phenomenon known as Green Sand Beach. Once you reach the edge of the landmark cinder cone, hike down cautiously on several well-worn paths to enjoy this amazing attraction. Congratulations! Very few visitors make it this far and your quest for Green Sand Beach is definitely one adventure that will stay with you for years to come.
