Seathwaite is a village in the Duddon Valley in the South Lakeland district of Cumbria in North West England. Historically in Lancashire, it lies within the Lake District National Park, and is part of the civil parish of Dunnerdale-with-Seathwaite, which has a population of 129. The nearby Seathwaite Tarn, west of the Coniston Fells, takes its
name from the village. The village is north east of Hall Dunnerdale and south west of the tarn. It lies along the old Walna Scar road, which can be reached from the A595 in the south, or from the steep Hardknott–Wrynose pass road in the north, which leads off the
A593 from Skelwith Bridge).
