Acid Beach is a kitesurfing spot located on the west coast of Oahu, in the Waianae area. This spot benefits from the north-east trade winds that wrap around the island, creating side-shore wind conditions. The body of water is open ocean with possible waves and currents. The bottom is a mix of sand and reef. The spot is suitable for advanced riders due to its exposure and distance from rescue services. Wild and uncrowded setting.
