Sequoia National Park

Log in to track your visit to Sequoia National Park.

Sequoia National Park is home to the largest trees on Earth by volume — giant sequoias so massive they defy easy comprehension. Standing before the General Sherman Tree, the world's largest single living organism by volume at 52,500 cubic feet, first-time visitors routinely fall silent. The base is 36 feet in diameter. The first major branch is larger than most full-grown trees in the eastern United States. Established in 1890 as America's second national park, Sequoia covers 404,000 acres of the southern Sierra Nevada and is managed jointly with neighboring Kings Canyon National Park. Together they protect the world's largest concentration of giant sequoias — trees that can live over 3,000 years and that require fire to reproduce, their cones sealed shut with resin until heat opens them. The park's elevation range is extraordinary: from 1,370 feet in the subtropical foothills along the Kaweah River to 14,494 feet at the summit of Mount Whitney — the highest peak in the contiguous United States — all within a single park boundary. Below the sequoia groves, chaparral-covered foothills bloom with wildflowers in spring; above them, granite domes and ridges rise into a sky-island alpine world. Crystal Cave, a marble cavern discovered in 1918, adds underground drama to a park already rich in superlatives.

The Congress Trail is the single most rewarding walk in the park — a paved 2-mile loop from the General Sherman Tree through the Giant Forest grove, passing the President, Lincoln, McKinley, and Chief Sequoyah trees. It's largely flat, accessible to most abilities, and completely surrounded by the largest trees on Earth. For a longer experience, the High Sierra Trail begins at Crescent Meadow and traverses 72 miles to Mount Whitney — one of California's great multi-day backpacking routes. Moro Rock is a granite dome you can summit via a 0.6-mile staircase trail for panoramic views of the Great Western Divide and the sequoia forest below. Crystal Cave offers guided tours May through November; tickets must be purchased in advance at the Foothills or Lodgepole visitor centers, not at the cave itself. The Lakes Trail (13 miles round trip) leads from Wolverton to the pristine Heather, Aster, Pear, and Emerald lakes — an excellent high-country day hike. The Tokopah Falls Trail (3.4 miles round trip) follows the Marble Fork of the Kaweah River to a dramatic 1,200-foot waterfall. Snowshoeing through Giant Forest in winter, when the park is nearly empty, is a truly magical experience.

Black bears are the park's most famous wildlife residents, and encounters are common — the park uses bear boxes at all campgrounds and trailheads, and food storage regulations are strictly enforced. Mule deer browse the sequoia groves and meadows. Steller's jays are brazen campsite visitors. The foothills support western fence lizards, foothill yellow-legged frogs, and California kingsnakes. At higher elevations, marmots sunbathe on granite boulders, pika dart through talus fields, and golden eagles drift on thermals. The park's old-growth forest supports spotted owls and great gray owls — both rarely seen but reliably present.

Sequoia and Kings Canyon are managed together with a single $35 vehicle entrance fee valid for seven days at both parks. The Generals Highway connecting the parks can be closed in winter for snow plowing — check road conditions. Lodgepole and Dorst Creek campgrounds can be reserved in advance through Recreation.gov; several campgrounds are first-come, first-served. The Wuksachi Lodge inside the park is the only in-park hotel; book months ahead. Crystal Cave tickets sell out — buy online before your visit date. The park is open year-round but access is limited in winter.

Sequoia is about 55 miles east of Visalia in the southern Sierra Nevada. From Visalia, take CA-198 east through Three Rivers to the Ash Mountain entrance. From Fresno, take CA-180 east through Kings Canyon's Big Stump entrance — this road connects to Sequoia via the Generals Highway. The nearest major airports are Fresno Yosemite International (FAT) and Visalia Municipal Airport (VIS). During summer, the Sequoia Shuttle connects Visalia to the Giant Forest.

Never leave food in your car, even for five minutes — black bears have learned to recognize coolers and will smash windows to reach them. Crystal Cave tickets must be purchased in advance (not at the cave); the cave road is also closed to RVs and trailers. The General Sherman Tree parking area fills by 9 a.m. on summer days; take the shuttle from Wuksachi Lodge or Lodgepole instead. Sequoia's air quality can be poor in summer due to Central Valley smog; the NPS posts air quality advisories on the website. Bring chains or four-wheel drive in winter — the Generals Highway at 6,000–7,000 feet frequently requires them.
