Lake Windermere is located in Cumberland, next to Bowness-on-Windermere in Northwest England's Lake District. The lake, largest in England, is over 10 miles long, and during the summer, cruises, fishing, boating, sailing and scuba diving are popular with visitors.
The bed of the lake was formed by glacial action. The shores are much indented and generally low, but steep sided. There are several wooded islets in the lake, which is drained by the Leven into Morecambe Bay. The towns of Windermere and Ambleside are along the lake.
