Humboldt-Toiyabe National Forest

At 6.3 million acres, the Humboldt-Toiyabe is the largest national forest in the contiguous United States, scattered across Nevada and a small portion of eastern California in a pattern that mirrors the state's basin-and-range geography. Rather than forming a single contiguous block, the forest comprises isolated mountain ranges rising like forested islands from the Great Basin desert -- the Ruby Mountains, the Santa Rosa Range, the Toiyabe Range, the Spring Mountains, and many others. This unique distribution makes it one of the most geographically diverse forests in the entire National Forest System.\n\nTen designated wilderness areas protect the forest's most pristine landscapes, including the Jarbidge Wilderness (one of the most remote areas in the lower 48), the Ruby Mountains Wilderness dubbed the "Alps of Nevada," and the Mount Charleston Wilderness rising dramatically above Las Vegas. Ancient bristlecone pine groves cling to windswept ridges, and the forest supports Nevada's last populations of Lahontan cutthroat trout and bull trout.\n\nDespite its immense size, Humboldt-Toiyabe remains one of the least visited national forests, offering genuine solitude rarely found on western public lands. The Ruby Crest Trail traverses 43 miles through the Ruby Mountains, widely regarded as one of America's finest but least-known backpacking routes. The Spring Mountains National Recreation Area near Las Vegas sees heavy year-round visitation for hiking, camping, and winter skiing at Lee Canyon.
