Tioga Pass (el. 9,943 ft. / 3,031 m.) is a mountain pass in the Sierra Nevada mountains of California. State Route 120 runs through it, and serves as the eastern entry point for stunning Yosemite National Park, a World Heritage site. It is the highest highway pass in California and in the Sierra Nevada. 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 (914 m) by the time the road reaches U.S. Route 395.
