The Lyth Valley sits in the south-eastern corner of the Lake District. The River Gilpin runs down the middle of the valley, which is famous for its damson orchards. The valley is overlooked to the east by the Scout Scar and the hills west of Sizergh Castle and to the west by the eastern slopes of Whitbarrow, giving it a sheltered climate.
Every year there is a Damson Day held in the valley.
Park End Moss, near Brigsteer, has recently been turned from farm land into a wetland reserve.
