The Hallstatt salt mine is the oldest known salt mine in the world, with continuous extraction recorded back to at least 5,000 BCE. The site sits on the Salzberg high above the village, reached by a steep funicular railway from a station next to the bus park.
The visit takes about ninety minutes and includes the funicular ride, a short walk along the open-air Skywalk with its panoramic platform over the lake, and then the mine tour itself. Visitors don miners' overalls and slide down two long wooden chutes (the longer is 64 metres) between the levels — exactly as miners did for centuries. The displays cover the Hallstatt Iron Age culture, the discovery of the Man in Salt, and a glass-floored chamber over the world's oldest preserved wooden staircase. Closed in winter; book online to skip the queues in high season.
