The birthplace of big-wave surfing. When winter NW swells exceed 20 ft the bay comes alive and the Eddie runs. In summer it turns glassy and flat — swim and jump off the rock instead.

Safety: Expert-only water — heavy hold-downs, strong currents and serious consequences. Paddle out only at sizes you have real experience in, and never alone. Shallow reef or coral — know the tide stage and where the channel is before you paddle out. Sharks are part of the ecosystem here — avoid dawn, dusk and murky rivermouth water.
