Tioga Pass

Tioga Pass is a mountain pass in the Sierra Nevada 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 highway pass in California and in the Sierra Nevada. Mount Dana is to the east of the pass. 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 rough 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.

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 feet by the time the road reaches U.S. Route 395.
