Why Sequoia National Park
Located in the southern Sierra Nevada east of Visalia, California, Sequoia National Park encompasses over 400,000 acres of mountainous and forested terrain. Established on September 25, 1890, as the second national park in the United States, it is contiguous with and jointly administered alongside Kings Canyon National Park by the National Park Service, with both areas recognized as a UNESCO biosphere reserve since 1976. The park spans a vertical relief of nearly 13,000 feet and includes Mount Whitney, which reaches 14,505 feet above sea level as the highest summit in the contiguous nation.
The park features diverse geological and ecological zones. Lower elevations near the entrance at Ash Mountain host a California Foothills ecosystem with blue oak woodlands, chaparral, grasslands, and mild river valleys. As elevation rises between 5,500 and 9,000 feet, the landscape transitions into coniferous montane forests of pine, fir, and giant sequoias, interspersed with seasonal meadows formed by snowmelt. High ridges like the Great Western Divide boast peaks exceeding 12,000 feet, while dramatic chasms such as Tokopah Valley and the 5,000-foot-deep Kern Canyon cut through the terrain. Roughly 84 percent of the park is protected, roadless backcountry accessible strictly on foot or horseback.
Sequoia National Park is world-famous for its massive old-growth giant sequoia trees. Within the Giant Forest, visitors can view five of the ten largest trees on Earth, including the General Sherman Tree, which holds the record as the world's largest living single-stem tree by volume. The Generals Highway links this grove to General Grant Grove in neighboring Kings Canyon National Park. Additional points of interest include Moro Rock, Mineral King—a high-elevation former mining district popular among backpackers—and historical structures such as Tharp's Log, a dwelling built inside a hollowed sequoia trunk by the region's first European settler.
Human history in the area dates back to at least AD 1000. Indigenous groups, including the Monache, Tübatulabal, Yokuts, Owens Valley Paiute, and Shoshone, long inhabited or utilized these lands. Archaeological evidence includes bedrock mortars and ancient pictographs at sites like Hospital Rock and Potwisha. Following 19th-century European settlement and indigenous displacement, early military management was carried out by segregated African-American troops known as the Buffalo Soldiers under Captain Charles Young, who constructed park infrastructure and advanced early conservation efforts.
Visitors entering via the southern route near Three Rivers encounter a varied climate that spans five classification types based on elevation, ranging from hot Mediterranean foothill zones to subarctic and tundra conditions near the high peaks. Wildlife inhabiting these diverse environments includes mule deer, bobcats, foxes, Douglas squirrels, and American black bears, along with reclusive species such as Pacific fishers and mountain lions.
