Lake Tahoe is a large freshwater lake in the Sierra Nevada of the United States. Lying at 6,225 ft (1,897 m), it straddles the state line between California and Nevada, west of Carson City. Lake Tahoe is the largest alpine lake in North America, and at 122,160,280 acre⋅ft (150.7 km3) it trails only the five Great Lakes as the largest by volume in the United States. Its depth is 1,645 ft (501 m), making it the second deepest in the United States after Crater Lake in Oregon (1,949 ft or 594 m).

It is also very clear, with visibility more than 70 feet in spots and a gorgeous fusion of blue hues that change with the weather and the portion of the lake.

In summer, Lake Tahoe attracts sunbathers to its shores, although the water stays pretty cold year-round. In winter, there is skiing in the mountains, with panoramic lake views from the runs.
