Sequoia National Park is a national park in the southern Sierra Nevada, east of Visalia, California, in the United States of America. It was established on September 25th, 1890. The park spans 404,051 acres (1,635 km2). 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.

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, in terms of wood volume. The Giant Forest is connected by the park's Generals Highway to Kings Canyon National Park's Grant Grove, home to the General Grant tree among other 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.

Front country

Many park visitors enter Sequoia National Park through its southern entrance near the town of Three Rivers at Ash Mountain at 1,700 ft (520 m) elevation. The lower elevations around Ash Mountain contain the only National Park Service-protected California Foothills ecosystem, consisting of blue oak woodlands, foothills chaparral, grasslands, yucca plants, and steep, mild river valleys. The foothills region is also home to abundant wildlife: bobcats, foxes, ground squirrels, rattlesnakes, and mule deer are commonly seen in this area, and more rarely, reclusive mountain lions are seen as well. The California Black Oak, Quercus kelloggii, is a key transition species between the chaparral and higher elevation conifer forest.

At higher elevations in the front country, between 5,500 and 9,000 feet (1,700 and 2,700 m) in elevation, the landscape becomes montane forest-dominated coniferous belt. Found here are Ponderosa, Jeffrey, Sugar, and Lodgepole pine trees, as well as abundant white and red fir. Found here too are the mighty Sequoia trees, the most massive living trees on earth. Between the trees, spring and summer snowmelts sometimes fan out to form lush, though delicate, meadows. In this region, visitors often see mule deer, Douglas squirrel, and American black bears, who have been known to break into unattended cars to steal food left by careless visitors.

Back country

The vast majority of the park is roadless wilderness; in fact, to the surprise of many visitors, no road crosses the Sierra Nevada within the park's boundaries. 84% of Sequoia and Kings Canyon National Parks is designated as Wilderness and is accessible only by foot or by horse.

Sequoia's backcountry offers a vast expanse of high-alpine wonders. Covering the highest-elevation region of the High Sierra, the backcountry includes Mount Whitney on the eastern border of the park, accessible from the Giant Forest via the High Sierra Trail. On a traveler's path along this 35-mile (56 km) backcountry trail, one passes through about 10 miles (16 km) of montane forest before reaching the backcountry resort of Bearpaw Meadow, just short of the Great Western Divide. Bearpaw Meadow offers rustic tent cabins and gourmet meals cooked by a seasonal resident park crew.

Continuing along the High Sierra Trail over the Great Western Divide via Kaweah Gap, one passes from the Kaweah River Drainage, with its characteristic V-shaped river valleys, and into the Kern River drainage, where an ancient fault line has aided glaciers in the last ice age to create a U-shaped canyon that is almost perfectly straight for nearly 20 miles (32 km). On the floor of this canyon, at least 2 days hike from the nearest road, is the Kern Canyon hot spring, a popular resting point for weary backpackers. From the floor of Kern Canyon, the trail ascends again over 8,000 ft (2,400 m) to the summit of Mount Whitney.

At Mount Whitney, the High Sierra Trail meets with the John Muir Trail and the epic Pacific Crest Trail, which continue northward along the Sierra crest and into the backcountry of Kings Canyon National Park.

Park attractions

In addition to hiking, camping, fishing, and backpacking, the following attractions are highlights with many park visitors:

*Tunnel Log is a tunnel cut through a fallen giant sequoia tree in Sequoia National Park in California. The tree, which measured 275 feet (84 m) tall and 21 feet (6.4 m) in diameter, fell across a park road in 1937 due to natural causes. The following year, a crew cut an 8-foot (2.4 m) tall, 17-foot (5.2 m) wide tunnel through the trunk, making the road passable again.

*Crescent Meadow is a small, sequoia-rimmed meadow in the Giant Forest region of Sequoia National Park. This sierran montane meadow marks the western terminus of the High Sierra Trail, which stretches from the meadow across the Great Western Divide to Mount Whitney. Pioneer Hale Tharp homesteaded in this and nearby Log Meadow. Conservationist John Muir visited this meadow many times and praised it highly calling it the "Gem of the Sierras". The meadow lies at the end of a three mile paved road which leaves the Generals Highway near the Giant Forest Museum.

*Moro Rock is a granite dome located in the center of the park, at the head of Moro Creek, between Giant Forest and Crescent Meadow. A 400-step stairway, built in the 1930s by the Civilian Conservation Corps, is cut into and poured onto the rock, so that visitors can hike to the top. The stairway is listed on the National Register of Historic Places. The view from the rock encompasses much of the Park, including the Great Western Divide. It has an elevation of 6,725 feet (2,050 m).

*Campgrounds in the park include three in the foothills area: Potwisha (42 sites), Buckeye Flat (28 sites), and South Fork (10 sites). Four campgrounds are at higher, conifer-dominated elevations, ranging from 6,650 to 7,500 feet (2,000 to 2,300 m): Atwell Mill (21 sites), Cold Springs (40 sites), Lodgepole (214 sites), and Dorst (204 sites).
