Exmoor is a National Park situated on the Bristol Channel coast of South West England. The park straddles two counties with 71% of the park located in Somerset and 29% located in Devon. The total area of the park, which includes the Brendon Hills, the East Lyn Valley and the Vale of Porlock, covers 692.8 square kilometres (267.5 sq mi) of hilly open moorland and includes 55 kilometres (34 mi) of coast. It is primarily an upland area with a dispersed population living mainly in small villages and hamlets. The largest settlements are Porlock, Dulverton, Lynton, and Lynmouth, which together contain almost 40% of the National Park population. Lynton and Lynmouth are combined into one parish and are connected by the Lynton and Lynmouth Cliff Railway.
