The Banzai Pipeline, or simply "Pipeline" or "Pipe", is a surf reef break located off Ehukai Beach Park in Pupukea of O`ahu's North Shore. A reef break is an area in the ocean where waves crash once they reach the shallows of a reef. Pipeline is notorious and famous for its huge waves breaking in shallow water just above its sharp and cavernous reef forming large, hollow and thick curls of water (a.k.a., tubes or barrels) that surfers can surf inside of and hopefully escape from using expert tube riding abilities. There are at least three reefs at Pipeline in progressively deeper water further out to sea that activate at various power levels applied by ocean swells.
