Located on Maui’s Kaihalulu Bay, Red Sand Beach is a pocket beach surrounded by red lava cliffs along a rugged coastline. A black offshore reef protects the bay from large waves, making the blue waters here calmer, and the erosion of the nearby iron-rich cinder cone has turned the sand red, making for a breathtakingly stark contrast. Mostly known among locals, the extremely remote beach is a bit dangerous to get to; the trail leading to Red Sand Beach is on a high ridge and is steep and narrow, as well as slippery. As a result of its isolation, many beachgoers here have been known to go clothing-optional.
