At this 100-year-old mine, you can take a guided tour 1,000 feet underground, pan for gold in Eureka Creek, explore the mining exhibit and the five-story 75-year-old mill, and listen to the legends. The mine is a constant 45°F (7°C) year-round, so take a jacket even in August. There are also a restored blacksmith shop, indoor gold panning in winter, and sleigh rides available in the snowy months ( Burros also roam around, posing for pictures with children; every summer sees the addition of a baby burro. Tours start on the hour. Allow at least an hour.
