World's Strangest Beaches
Papakolea Beach, Hawaii
It takes effort to reach Papakolea. The beach is located near Ka Lae, the southernmost point in Hawaii—and the entire United States. To reach it, visitors endure a hot and rugged hike for nearly three miles along sea cliffs. The reward: ending up on a green-sand beach. The grains are almost pure olivine, a green mineral, and come from Puu Mahana, a volcanic cone that sits above the beach.
