Buttermere lake, famous for its beautiful setting among the northern fells, is correctly called just ‘Buttermere’. This means ‘the lake by the dairy pastures’. It is 1.24 miles (2 km) long, 620 yards (570 m) wide and 75 feet (23 m) deep. The classic combination of lakes and mountains has made this popular with visitors since the beginning of tourism in the Lake District.
