Tatshenshini-Alsek Provincial Park occupies a remote corner of northwestern British Columbia, between Alaska and the Yukon. It protects about 9,580 square kilometres of mountains, glaciers, rivers and valleys, a landscape that shifts from coastal influence toward the continental interior. The Haines Highway runs along the park’s eastern side, but no road crosses the park itself. The distinction matters to visitors: roadside access opens some trailheads, while much of the protected area remains accessible only by demanding backcountry routes or river journeys.
The park was established in 1993 after conservation campaigns challenged proposed mining development in the region. In 1994, Tatshenshini-Alsek was added to the UNESCO World Heritage property that also includes Kluane, Wrangell–St. Elias and Glacier Bay. Together the protected areas form an exceptional transboundary landscape of high peaks, icefields and long glaciers. UNESCO describes the connected property as containing the world’s largest non-polar icefield and as a place where glacial, tectonic and river processes remain active.
