These two famous rivers merge as one, yet each is celebrated for unique features and distinctive experiences. Together, the Tatshenshini and Alsek deliver the best of northern wildlife, glacier views and diverse ecosystems while passing through a spectacular mountain landscape recognized as a UNESCO World Heritage site and the world’s largest international protected area.

In the ultimate double-whammy, both the Alsek and Tashenshini rivers are recognized as Canadian Heritage Rivers, a distinction given to a select group of special rivers in Canada. The surrounding region contains some of the world’s most active glaciers and healthy populations of grizzlies, bald eagles, moose, wolves and other animals.

The Alsek starts in Kluane National Park, flowing from Canada’s highest mountains. Some of the world's longest mountain glaciers flow into the silty Alsek, calving icebergs into the river. Rafting down the Alsek is a journey through a land gripped in rock and ice, and the river’s remoteness, beauty and wild rapids impress the hardiest of adventurers.

The Tatshenshini begins along the scenic Haines Highway, part of the Golden Circle drive. The 'Tat' is an equally spectacular river that boasts fantastic rapids, canyons and superb wildlife viewing in the majestic Coast Mountains. The Tatshenshini is an important salmon spawning river, and the Champagne and Aishihik people traditionally harvested salmon along the river and at the village of Klukshu. Yukon operators offer river rafting expeditions on both rivers.
