Forests are the quintessential wild lands. Animals, insects and plants of all kinds live in forested habitats, and some of the most magnificent views in the nation can be found within the pines and leafy trees of our public lands. Among our plentiful National Forests and Grasslands there are a few that stand out as titans. The largest national forests in the U.S. are spread out all along the western half of the country, north to Alaska, and south to Arizona. Diverse populations of animals—including endangered species—live, play and depend on these lands. We invite you to visit the mammoth tracts of land. After all, you’re a co-owner. It’s all yours.

The largest National Forest in the nation and a humongous land area, the Tongass surrounds the Inside Passage. As you explore Southeast Alaska you can see remnants of the vast glaciers that formed much of the North American landscape. At more than 17 million acres, the Tongass is an incredible testament to conservation and nature.

Just outside of Anchorage, the Chugach National Forest is a gem within the National Forest System. At more than 5 million acres, the Chugach would take a lifetime to fully explore! Glacier Ranger District holds the remains of the ice masses that shaped the topography of the North American continent and boasts abundant wildlife—even killer whales! Crow Pass Trail Thru-Hike, Flattop Mountain, Williwaw Lakes and Mount Elliot are among the incredible outdoor opportunities in this region; plus, Prince William Sound backs right up to the Chugach Mountains, making for some epic glacier-hunting and water exploration.
