Take a tour of the largest of the 250 riverboats that chugged up and down the Yukon River between 1929 and 1955, primarily as a cargo transport. Actually, the one on view was built in 1936 to replace the first Klondike, which ran aground. The Klondike is now permanently dry-docked beside the river and is a designated National Historic Site. The boat has been restored to its late-1930s glory.
