Banyans

Kona Coast, Big Island, USA (HI)
🪸Sharp reef🌀Strong rips

Banyans is the Big Island's best wave—an A-frame reef break that catches both W/NW swells in winter and S swells in summer, making it one of Hawaii's most versatile spots. Long, glassy rights in Kona conditions are the specialty. Shane Dorian's home break.
