Arthur Ransome set his children's novel "Swallows and Amazons" and the sequels "Swallowdale", "Winter Holiday", "Pigeon Post" and "The Picts and the Martyrs" around a fictional lake derived from a combination of Coniston Water and Windermere. The fictional lake resembles Windermere, but the surrounding hills and fells resemble those of Coniston Water. Some of Coniston Water's islands and other local landmarks can be identified in the novels. In particular the books' "Wild Cat Island" with its secret harbour is based on Peel Island. The Amazon River is based on the River Crake. The Swallows and Amazons series involve school holiday adventures in the 1930s.
