Denali National Park and Beyond, Alaska and Canada
The northern boreal forests occupy great swaths of land from Alaska’s dramatic Denali National Park all the way to the Wood Buffalo National Park in Alberta, Canada (at 17,000 square miles, it’s the largest national park in the country).
How to Go: Country Walkers’ six-day trek aims to give visitors an experience from every angle: from the ground (hiking), from the air, and from a train. Bed down at North Face Lodge with spectacular views of six major peaks of the Alaska Range.
