Remarkable Cave

Remarkable Cave, at the end of Safety Cove Road south of Port Arthur, is a striking natural rock formation on Tasmania's rugged Tasman Peninsula. A short boardwalk and stairway lead down to a viewing platform where you can look through the sea-carved cave to the wild Southern Ocean beyond — a dramatic, elemental slice of Tasmania's famous coastline.

The surrounding scenery is every bit as compelling as the cave itself, with towering cliffs, crashing surf and the start of some of the peninsula's spectacular coastal walks. It pairs naturally with a visit to the historic Port Arthur site nearby, rounding out a day exploring one of the most scenic and storied corners of the state.

With a 4.7 rating from more than 1,600 reviews, it's a firmly established favourite. The site is free and open, but the stairs and viewing area are exposed to the weather, conditions can be wild and access can change, so it's worth checking current details before you go — and taking warm, weatherproof layers and sturdy footwear, and keeping well back from the cliff edges and surf.
