Sail in the shadow of the tallest sea cliffs in the Southern Hemisphere and witness the power of the ocean as it surges out of deep sea caves on a three-hour wilderness cruise from Port Arthur. Marvel at soaring rock formations, cascading waterfalls and natural archways before casting your eyes towards the water where you might spy a frenzy of diving sea eagles or a pod of cheeky dolphins, seals or whales. Immerse yourself in three hours of rugged wonder as you hug the coast between Port Arthur and Eaglehawk Neck in southern Tasmania.
