The River Exe ( EKS) in England rises at Exe Head, near the village of Simonsbath, on Exmoor in Somerset, 8.4 kilometres (5 mi) from the Bristol Channel coast, but flows more or less directly due south, so that most of its length lies in Devon. It flows for 60 miles (96 km) and reaches the sea at a substantial ria, the Exe Estuary, on the south (English Channel) coast of Devon.
