A train such as you would find at an amusement park carries visitors though an impressively staged educational tour, including a trip through a tunnel in the permafrost. This is like a land version of the riverboat tour that's operated by the same family. But the gold miners who act as hosts are the real attraction here. Visitors gather around a sluice to hear the amusing and authentic Dexter and Lynette (also known as Yukon Yonda) Clark and watch a swoosh of water and gold-bearing gravel rush by. You pan the resulting pay dirt, and everyone goes home with enough gold dust to fill a plastic locket -- typically $5 to $35 worth. Drive out to the mine after making reservations, or take a $5 shuttle.
