Tongass National Forest

The Tongass National Forest in Southeast Alaska is the largest U.S. National Forest at 16.7 million acres, an expanse larger than 10 U.S. states and 75 U.N. member nations. Most of its area is temperate rain forest and is remote enough to be home to many species of endangered and rare flora and fauna. The Tongass, which is managed by the United States Forest Service, encompasses islands of the Alexander Archipelago, fjords and glaciers, and peaks of the Coast Mountains. An international border with Canada runs along the crest of the Boundary Ranges of the Coast Mountains. The forest is administered from Forest Service headquarters offices in Ketchikan. There are local ranger district offices located in Craig, Hoonah, Juneau, Ketchikan, Petersburg, Sitka, Thorne Bay, Wrangell, and Yakutat.
