Ma'alaea

South Coast, Maui, USA (HI)
🪸Sharp reef🌀Strong rips⚠️Shallow

Ma'alaea (Freight Trains) is considered the world's fastest rideable wave—a 150-300+ yard barrel that fires only a handful of times per year when huge south swells slip through the gap between Kahoolawe and Maui. When it runs, it's one of surfing's greatest spectacles.
