Lake Windermere is the largest lake in England, part of what is often called the Lake District. Located in Cumbria, it has been one of the country's most popular places for vacations and summer homes since 1847, when the Kendal and Windermere Railway Company built a branch line to it.

Windermere is 10 1/2 miles long and roughly one mile wide, reaching a depth of about 220 feet. It is bordered on the south by ranges of hills that provide panoramic views and have long been popular with hikers.

The only town on the lake is Ambleside. Windermere town is actually a short distance away.

Racer Norman Buckley set several world waterspeed records on Lake Windermere in the 1950s.
