Tioga Lake is a small glacial lake in the Inyo National Forest of Mono County, California, about two miles north of the Tioga Pass entrance to Yosemite National Park. The lake bed is alongside State Route 120 in the Sierra Nevada mountains of northern California. The lake, at an altitude of almost 10,000 feet is one of the last parts of Yosemite to open for the season. The lake area offers spectacular views, as well as trout fishing, a picnic area, and a 13-site managed campground. Some of the wildlife in the area are brave enough to approach humans, especially birds and marmots. Occasionally a bobcat or bighorn sheep can be seen, although the latter are particularly shy.
