The Emigrant Wilderness of Stanislaus National Forest is a wilderness area in the Sierra Nevada. It is bordered by Yosemite National Park on the south, the Toiyabe National Forest and the Hoover Wilderness on the east, and State Route 108 over Sonora Pass on the north. It is an elongated area that extends northeast about 25 miles (40 km) in length and up to 15 miles (24 km) in width. Watersheds drain to the Stanislaus and Tuolumne Rivers. The Emigrant Wilderness area, which is a glaciated landscape, is entirely within Tuolumne County, California and is approximately 140 miles (230 km) east of San Francisco, California and 50 miles (80 km) south of Lake Tahoe.

Yosemite National Park is a national park in California. It is bordered on the southeast by Sierra National Forest and on the northwest by Stanislaus National Forest. The park is managed by the National Park Service and covers 759,620 acres in four counties – centered in Tuolumne and Mariposa, extending north and east to Mono and south to Madera. Designated a World Heritage Site in 1984, Yosemite is internationally recognized for its granite cliffs, waterfalls, clear streams, giant sequoia groves, lakes, mountains, meadows, glaciers, and biological diversity. Almost 95 percent of the park is designated wilderness. Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada.
