Shipstern Bluff

Tasmania, Australia
🦈Sharks😮‍💨Hold-downs🏝️Remote⚠️Shallow🚶Difficult access

Shipstern Bluff is one of the most terrifying waves on the planet—a Tasmanian slab famous for its mutant "steps" that form mid-face as the wave throws over a shallow reef ledge. Located at the end of a remote Tasman Peninsula, Shipstern requires either a 2-hour hike through rugged national park or a long jet-ski ride through great white shark territory. The wave is cold, isolated, unpredictable, and thoroughly hostile to human beings. Yet the barrels are other-worldly. This is big wave surfing at its most raw and unforgiving.
