Bordering Yosemite National Park to the northwest is Stanislaus National Forest. This forest was established in 1897 and preserves nearly 900,000 acres for recreation, forestry, grazing and other natural uses. The forest contains 500 miles of hiking trails and 800 miles of rivers and streams. It was named after a local Native American leader named Estanislao, though slightly modified.
When driving between Yosemite and Hetch Hetchy Reservoir, you will drive through Stanislaus.
