Tongass National Forest
Tongass National Forest (USDA Forest Service) · Ketchikan, Alaska
The largest national forest in the United States, covering about 16.7 million acres of Southeast Alaska — most of the Inside Passage — in one of the world's largest remaining temperate rainforests. Giant Sitka spruce, western hemlock and cedar grow among fjords, tidewater glaciers and thousands of islands, and rain can pass 150 inches a year in places. It holds Mendenhall Glacier, Misty Fiords and Admiralty Island national monuments, Tracy Arm-Fords Terror and more than a dozen other wilderness areas, and around 150 public-use cabins. Bears feed at salmon streams such as Anan Creek, and the LeConte Glacier near Petersburg is the southernmost tidewater glacier in the Northern Hemisphere. In August 2026 the government proposed removing Roadless Rule protections nationwide, with public comments due by 21 September 2026.
