Sequoia National Park is a national park in the southern Sierra Nevada east of Visalia, California, in the United States. It was established on September 25, 1890. The park spans 404,064 acres (631.35 sq mi; 163,518.90 ha; 1,635.19 km2).[1] Encompassing a vertical relief of nearly 13,000 feet (4,000 m), the park contains among its natural resources the highest point in the contiguous 48 United States, Mount Whitney, at 14,505 feet (4,421 m) above sea level. The park is south of and contiguous with Kings Canyon National Park; the two are administered by the National Park Service together as the Sequoia and Kings Canyon National Parks. They were designated the UNESCO Sequoia-Kings Canyon Biosphere Reserve in 1976.

The park is famous for its giant sequoia trees, including the General Sherman tree, the largest tree on Earth. The General Sherman tree grows in the Giant Forest, which contains five out of the ten largest trees in the world. The Giant Forest is connected by the Generals Highway to Kings Canyon National Park's General Grant Grove, home to the General Grant tree among other giant sequoias. The park's giant sequoia forests are part of 202,430 acres (81,921 ha) of old-growth forests shared by Sequoia and Kings Canyon National Parks. Indeed, the parks preserve a landscape that still resembles the southern Sierra Nevada before Euro-American settlement.
