Part of the world's largest bio-preserve, the Tatshenshini flows through the Yukon, B.C., Alaska, Glacier Bay National Park, Alsek/Tatshenshini Provincial Park, out to the Gulf of Alaska. Perhaps the wildest and most visually spectacular river in North America, the Tatshenshini flows through the heart of the largest bio-preserve in the world. The Tatshenshini courses among the tall spires of the Coast Range, vast glaciers and through a lake filled with huge icebergs. Bald Eagles abound, grizzlies feed on spawning salmon and if you’re lucky, you might catch a glimpse of the rare blue glacier bear. This adventure on the Tat is an international journey of unparalleled beauty. You'll raft from the Klukshu River, a Coast Range river at Dalton Post to Dry Bay, at the Gulf of Alaska along a 255-kilometre (160 mile) route with an elevation drop of 550 metres (1800 feet).
