The Yukon is Alaska's largest river. It originates in Canada and flows 2,000 miles west into the Bering Sea. From the third week in May when the ice breaks up until mid-October when it re-freezes, it is a summer waterway.
After it freezes, it is a winter highway. Since Klondike Gold Rush days, the Yukon has seen heavy summer traffic by riverboats and steamers carrying freight during the summer months.
It is increasingly popular with recreational boaters, especially canoeists and rafters. The system also is an important fishery for arctic grayling, burbot, salmon, pike and whitefish. Access is by the Taylor Hwy and Steese Hwy.
