Six Rivers National Forest is a U.S. National Forest located in the northwestern corner of California. It was established on June 3, 1947 by U.S. President Harry S. Truman from portions of Klamath, Siskiyou and Trinity National Forests. Its over one million acres (4,000 km2) of land contain a variety of ecosystems and 137,000 acres (550 km2) of old growth forest. It lies in parts of four counties; in descending order of forestland area they are Del Norte, Humboldt, Trinity, and Siskiyou counties. The forest is named after the Eel, Van Duzen, Klamath, Trinity, Mad, and Smith rivers, which pass through or near the forest's boundaries.
The forest has 366 miles (589 km) of wild and scenic rivers, six distinct botanical areas, and public-use areas for camping, hiking, and fishing. The northernmost section of the forest is known as the Smith River National Recreation Area. Forest headquarters are located in Eureka, California. There are local ranger district offices in Bridgeville, Gasquet, Orleans, and Willow Creek.
Its old-growth forests include Coast Douglas-fir (Pseudotsuga menziesii var. menziesii), Tanoak (Lithocarpus densiflorus), Pacific madrone (Arbutus menziesii), and White Fir (Abies concolor).
There are five designated wilderness areas in Six Rivers National Forest that are part of the National Wilderness Preservation System. Two of them lie mostly in other National Forests or on Bureau of Land Management land.
The Klamath Mountains are a rugged and lightly populated mountain range in northwestern California and southwestern Oregon in the western United States. As a mountain system within both the greater Pacific Coast Ranges and the California Coast Ranges, the Klamath Mountains have a varied geology, with substantial areas of serpentinite and marble, and a climate characterized by moderately cold winters with very heavy snowfall and warm, very dry summers with limited rainfall, especially in the south. As a consequence of the geology and soil types, the mountains harbor several endemic or near-endemic trees, forming one of the largest collections of conifers in the world. The mountains are also home to a diverse array of fish and animal species, including black bears, large cats, owls, eagles, and several species of Pacific salmon. Millions of acres in the mountains are managed by the United States Forest Service. The northernmost and largest sub-range of the Klamath Mountains are the Siskiyou Mountains.
The Mendocino National Forest is located in the Coastal Mountain Range in northwestern California and comprises 913,306 acres (3,696 km2). It is the only national forest in the state of California without a major paved road entering it. There are a variety of recreational opportunities — camping, hiking, mountain biking, paragliding, backpacking, boating, fishing, hunting, nature study, photography, and off-highway vehicle travel.
The Siskiyou Mountains are a coastal subrange of the Klamath Mountains, and located in northwestern California and southwestern Oregon in the United States. They extend in an arc for approximately 100 miles (160 km) from east of Crescent City, California, northeast along the north side of the Klamath River into Josephine and Jackson counties in Oregon. The mountain range forms a barrier between the watersheds of the Klamath River to the south and the Rogue River to the north.

Forest headquarters are located in Medford, Oregon.
The Deschutes National Forest is a United States National Forest located in parts of Deschutes, Klamath, Lake, and Jefferson counties in central Oregon. It comprises 1.8 million acres (7,300 km2) along the east side of the Cascade Range. In 1908, the Deschutes National Forest was established from parts of the Blue Mountains, Cascade, and Fremont National Forests. In 1911, parts of the Deschutes National Forest were split off to form the Ochoco and Paulina National Forests, and parts of the Cascade and Oregon National Forests were added to the Deschutes. In 1915, the lands of the Paulina National Forest were rejoined to the Deschutes National Forest. A 1993 Forest Service study estimated that the extent of old growth in the forest was 348,100 acres (140,900 ha). Within the boundaries of the Deschutes National Forest is the Newberry National Volcanic Monument, containing cinder cones, lava flows, and lava tubes. The Deschutes National Forest as a whole contains in excess of 250 known caves. The forest also contains five wilderness areas, six National Wild and Scenic Rivers, the Oregon Cascade Recreation Area, and the Metolius Conservation Area. Forest headquarters are located in Bend, Oregon. There are local ranger district offices in Bend, Crescent, and Sisters.

The land was first set aside in April 1931 as the Marble Mountain Primitive Area, which comprised 234,957 acres (950.84 km2). It was one of four areas to gain primitive status under the Forest Service's L-20 regulations that year. In 1964, it became a federally designated wilderness area when the U.S. Congress passed the Wilderness Act.
The Bigfoot Trail is an unofficial U.S. long-distance hiking trail in northern California. The Bigfoot Trail was originally proposed by Michael Kauffmann in 2009 as a suggested route to navigate the Klamath Mountains from south to north as well as a long-trail to introduce nature lovers to the biodiversity of the Klamath Mountains region. The trail begins in the Yolla Bolly-Middle Eel Wilderness and ends in Redwood National Park at the Pacific Ocean near Crescent City, California. A major focus along the trail is conifer diversity, passing 32 species in 360 miles (580 km). The route crosses six wilderness areas, one National Park, and one State Park. Northwest California's Klamath Mountains foster one of the most diverse temperate coniferous forests on Earth, and this route is intended to be a celebration of that biodiversity.
