Finger Lakes

Eleven long, narrow lakes carved when Pleistocene ice sheets deepened north-flowing river valleys in central New York. Seneca and Cayuga, the two largest, each exceed 400 feet deep and moderate the local climate enough to support New York's largest wine region. Lake trout fishing, state parks, and gorge trails at Watkins Glen and Taughannock anchor recreation.
