It is situated on the western shore of Derwentwater within three miles of the busy tourist town of Keswick. Its distinctive shape catches the attention of many visitors to the Lakes who feel compelled to climb to the summit after seeing it from the viewpoint of Friars' Crag on the opposite side of Derwentwater.
