Tioga Pass is a mountain pass in the Sierra Nevada mountain range of California. State Route 120 runs through it, and serves as the eastern entry point for Yosemite National Park, at the Tioga Pass Entrance Station. It is the highest elevation highway pass in California and in the Sierra Nevada at an elevation of 9,945 ft (3,031 m). [1] [2] Mount Dana is to the east of the pass, and Gaylor Peak to the west.
Tioga Pass is named after Tioga Mine, whose name came from the Tioga River in New York: Tioga is an Iroquois and Mohawk term meaning "where it forks".[ citation needed ]
This pass, like many other passes in the Sierra Nevada, has a gradual approach from the west and drops off to the east dramatically, losing more than 3,000 ft (910 m) by the time the road reaches U.S. Route 395.
The pass is subject to winter closure due to high snowfall, normally from around the end of October until the end of May the following year, though these dates are subject to considerable variation. In heavy snow years, the road has closed in early October, and has remained closed as late as late July. In light snow years, the road may remain open until December and open as early as April.

Tioga Pass is the most direct route from Bishop or Mammoth Lakes, California to Fresno, Merced, and Stockton. There are four highway passes to the north, between Yosemite and Lake Tahoe, but none to the south for about 200 mi (320 km), until Sherman Pass in southern Tulare County.
The pass is on the Great Basin Divide, which demarcates the Great Basin, which is the largest contiguous area of endorheic basins in North America.
There are several trailheads into the Yosemite backcountry which begin at Tioga Pass, including the trail to the Gaylor Lakes to the west/northwest, and the trail to the summit of Mount Dana. Dana Meadows is immediately south of the pass alongside the highway, as the pass itself is roughly angled north–south as opposed to east–west. Dana Meadows contains several small lakes.
A popular recreation and camping area exists just north of the summit of the pass at Tioga Lake. It is in the Inyo National Forest.
Less than 7 miles to the southwest of the pass, inside Yosemite National Park, is Tuolumne Meadows. The Pacific Crest Trail passes through, and it crosses the highway here.
Although Tioga Pass doesn't have its own weather station, Ellery Lake, which is about 6 miles west does have a station that gives the expected climate found in Tioga Pass as well. The climate type for Tioga Pass is subarctic.

The Sierra Nevada is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas.
The John Muir Trail (JMT) is a long-distance trail in the Sierra Nevada mountain range of California, passing through Yosemite, Kings Canyon and Sequoia National Parks. It is named after John Muir, a naturalist.
Tuolumne Meadows is a gentle, dome-studded, sub-alpine meadow area along the Tuolumne River in the eastern section of Yosemite National Park in the United States. Its approximate location is 37°52.5′N119°21′W. Its approximate elevation is 8,619 feet (2,627 m). The term Tuolumne Meadows is also often used to describe a large portion of the Yosemite high country around the meadows, especially in context of rock climbing.
Mount Whitney is the highest mountain in the contiguous United States, with an elevation of 14,505 feet (4,421.2 m). It is in East–Central California, in the Sierra Nevada, on the boundary between California's Inyo and Tulare counties, and 84.6 miles (136.2 km) west-northwest of North America's lowest topographic point, Badwater Basin in Death Valley National Park, at 282 ft (86 m) below sea level. The mountain's west slope is in Sequoia National Park and the summit is the southern terminus of the John Muir Trail, which runs 211.9 mi (341.0 km) from Happy Isles in Yosemite Valley. The eastern slopes are in Inyo National Forest in Inyo County. Mount Whitney is ranked 18th by topographic isolation.
Mount Dana is a mountain in the U.S. state of California. Its summit marks the eastern boundary of Yosemite National Park and the western boundary of the Ansel Adams Wilderness. At an elevation of 13,061 feet (3,981 m), it is the second highest mountain in Yosemite, and the northernmost summit in the Sierra Nevada which is over 13,000 feet (3,962.4 m) in elevation. Mount Dana is the highest peak in Yosemite that accessible to summit. The mountain is named in honor of James Dwight Dana, who was a professor of natural history and geology at Yale.
Kings Canyon National Park is a national park of the United States in the southern Sierra Nevada, in Fresno and Tulare Counties, California. Originally established in 1890 as General Grant National Park, the park was greatly expanded and renamed on March 4, 1940. The park's namesake, Kings Canyon, is a rugged glacier-carved valley more than a mile (1,600 m) deep. Other natural features include multiple 14,000-foot (4,300 m) peaks, high mountain meadows, swift-flowing rivers, and some of the world's largest stands of giant sequoia trees. Kings Canyon is north of and contiguous with Sequoia National Park, and both parks are jointly administered by the National Park Service as the Sequoia and Kings Canyon National Parks.
Mount Gibbs is located in the Sierra Nevada of the U.S. state of California, 2.6 miles (4 km) south of Mount Dana. The mountain was named in honor of Oliver Gibbs, a professor at Harvard University and friend of Josiah Whitney. The summit marks the boundary between Yosemite National Park and the Ansel Adams Wilderness, and Mount Gibbs is the sixth-highest mountain, of Yosemite.
State Route 120 is a state highway in the central part of California, connecting the San Joaquin Valley with the Sierra Nevada, Yosemite National Park, and the Mono Lake area. Its western terminus is at Interstate 5 in Lathrop, and its eastern terminus is at U.S. Route 6 in Benton. While the route is signed as a contiguous route through Yosemite, the portion inside the park is federally maintained and is not included in the state route logs. The portion at Tioga Pass at Yosemite's eastern boundary is the highest paved through road in the California State Route system. This part is not maintained in the winter and is usually closed during the winter season.
Tenaya Lake is an alpine lake in Yosemite National Park, located between Yosemite Valley and Tuolumne Meadows. The surface of Tenaya Lake has an elevation of 8,150 feet (2,484 m). The lake basin was formed by glacial action, which left a backdrop of light granite rocks, whose beauty was known to the Native Americans. Today, Tenaya Lake is easily accessible by State Route 120 and is a popular lake for water activities.
Mount Lyell is the highest point in Yosemite National Park, at 13,114 feet (3,997 m). It is located at the southeast end of the Cathedral Range, 1+1⁄4 miles northwest of Rodgers Peak. The peak as well as nearby Lyell Canyon is named after Charles Lyell, a well-known 19th century geologist. The peak had one of the last remaining glaciers in Yosemite, Lyell Glacier. The Lyell Glacier is currently considered to be a permanent ice field, not a living glacier. Mount Lyell divides the Tuolumne River watershed to the north, the Merced to the west, and the Rush Creek drainage in the Mono Lake Basin to the southeast.
State Route 168 is an east-west state highway in the U.S. state of California that is separated into two distinct segments by the Sierra Nevada. The western segment runs from State Routes 41 and 180 in Fresno east to Huntington Lake along the western slope of the Sierra. The eastern segment connects Lake Sabrina in the Eastern Sierra to State Route 266 in the community of Oasis, just to the west of the Nevada border. The eastern segment of SR 168 also forms a concurrency with U.S. Route 395 between Bishop and Big Pine.
Sonora Pass is a mountain pass in the Sierra Nevada in California. It is the second-highest pass with a road in California and in the Sierra Nevada. It is 321 feet (98 m) lower than Tioga Pass to the south. State Route 108 traverses the pass, as does the Pacific Crest Trail.
U.S. Route 395 (US 395) is a United States Numbered Highway, stretching from Hesperia, California to the Canadian border in Laurier, Washington. The California portion of US 395 is a 557-mile (896 km) route which traverses from Interstate 15 (I-15) in Hesperia, north to the Oregon state line in Modoc County near Goose Lake. The route clips into Nevada, serving the cities Carson City and Reno, before returning to California.
The High Sierra Camps are nine rustic lodging facilities located in two national parks and a national monument in California's Sierra Nevada mountain range. Open most years from June or July to September, they are staffed camps with tent cabins and food service facilities. The backcountry camps receive their supplies by pack mules.
The Tahoe–Yosemite Trail (TYT) is a long-distance trail in the Sierra Nevada mountain range of California. The trail courses 186 miles (299 km) from Meeks Bay at Lake Tahoe to Tuolumne Meadows in Yosemite National Park. The trail is a foot and equestrian path that passes through the Desolation, Mokelumne, Carson-Iceberg, Emigrant, and Yosemite Wilderness Areas and the Meiss Country (Dardanelles) Roadless Area.
