Port Arthur Historic Site (Port Arthur).

Spread across more than 40 hectares of the Tasman Peninsula, the UNESCO World Heritage-listed Port Arthur Historic Site is one of Australia’s most evocative and intact convict-era settlements. Operating from 1830 to 1877 as both a penal colony and an industrial hub, the sprawling site features more than 30 preserved sandstone buildings, ruins, and manicured gardens set against the rugged beauty of Carnarvon Bay. A standard ticket spans two consecutive days and includes a harbor cruise, a self-guided audio experience, and site talks, giving visitors ample time to explore the dockyards, museum spaces, and nearby cliff walks. For a deeper look into its grim past, travelers can book specialized daytime tours or return after dark for lantern-lit ghost tours.
