Derwentwater is one of two lakes adjacent to Keswick, the other being Bassenthwaite. Derwentwater forms part of the Borrowdale valley, close to many of the Lake District's highest mountains, including Scafell Pike and Great Gable. There are superb views around the lake and famous landmarks, such as Ashness Bridge and the Bowder Stone, are close by. It is possible to walk all around the lake or use one of the jetties to catch a return boat if a shorter walk is preferred. There are plenty of visitor facilities in Keswick itself and refreshments are also available in the small hamlet of Grange, close to the south end of Derwentwater.
The Keswick Launch Company offers ferry services and cruises throughout the year. Launches start their journey at Keswick boat landings and circulate round the lake in either direction, calling at the seven jetties situated at various points round the shore. A full trip round the lake takes approximately 50 minutes
