Watersmeet House is a National Trust property located some 1.8 miles (2.9 km) east of Lynmouth, in the English county of Devon. A former fishing lodge, it is today used as an information centre, tea room and shop by the National Trust. Adjoining the house is the Watersmeet SSSI, a Site of Special Scientific Interest. The 348 hectares (860 acres) Watersmeet SSSI, partly situated on land also owned by the National Trust, includes an extensive area of ancient oak woodland. The woodland is notable for its endemic species of tree - the "No Parking Whitebeam" (Karpatiosorbus admonitor).
