The civil parish of Loweswater covers a considerable area around the village, and is bordered on its eastern side by the western shore of Crummock Water and by the River Cocker. To the north-west, the parish boundary is delineated by the summit of Fellbarrow, before encircling Loweswater lake via Low Fell and the A5086 road. From here, the parish boundary includes a large area of fell to the north and east of the summits of Blake Fell, Gavel Fell, Great Borne, Starling Dodd and Red Pike, before descending to Crummock Water.
