Hoover Wilderness, Nature reserve in Tuolumne County, California, US.

Hoover Wilderness is a wilderness area of about 48,601 acres in the Inyo and Humboldt-Toiyabe National Forests, east of the central Sierra Nevada crest and north and east of Yosemite National Park. It forms a long strip running nearly from Sonora Pass in the north to Tioga Pass in the south. Notable locations include Twenty Lakes Basin above Saddlebag Lake, Virginia Lakes Basin, and the Sawtooth Ridge with Matterhorn Peak.

The U.S. Forest Service first designated this area as a Primitive Area in 1931, giving it formal status within the national forest system. The wilderness designation came later, providing stricter protections for the landscape.

The wilderness takes its name from President Herbert Hoover, honored when the Forest Service designated the area in 1931. It was the setting of Camping Adventure, a children's book published in 1976 by the National Geographic Society in its Books for Young Explorers series.

Visitors need to obtain wilderness permits throughout the year, with stricter limitations during the busy summer season from late June through September. Planning ahead is important, especially if you want to hike during the peak hiking months.

This wilderness holds the headwaters of the East Walker River and connects directly to Yosemite National Park. The elevation rises dramatically from around 7,000 feet to over 12,000 feet, creating steep transitions between different zones.
