Azure blue skies and emerald green waters make up the magnificent Lake Tahoe and its surroundings. A large freshwater lake in the Sierra Nevada, Lake Tahoe is located along the border of the US states of California and Nevada. It is considered the largest alpine lake in North America and was formed about 2 million years ago. During the summer, the lake is perfect for water sports, including swimming and scuba diving. During winter, the area is draped in sheets of soft white snow that make for ideal skiing conditions. On top of gorgeous mountain and lake scenery, there are also ski resorts, casinos and many more tourist attractions here.
