Salzbergwerk

Once a major producer of "white gold," Berchtesgaden has thrown open its salt mines (salzbergwerk.de; adult/student/child €25.50/22.50/13) for fun-filled 1½-hour tours. Kids especially love donning miners’ garb and whooshing down a wooden slide into the depths of the mine. Down below, highlights include mysteriously glowing salt grottoes and crossing a 100m-long subterranean salt lake on a wooden raft. Take hourly bus 840 from Berchtesgaden train station.
