The River Exe in England rises at Exe Head, near the village of Simonsbath, on Exmoor in Somerset, 5.2 miles (8.4 km) 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 coast of Devon. Historically, its lowest bridging point was the Old Exe Bridge in Exeter, the largest settlement on the river, but there is now a viaduct for the M5 motorway about 2 miles (3.2 km) south of the city centre.

Simonsbath is a small village high on Exmoor in the English county of Somerset. It is the principal settlement in the Exmoor civil parish, which is the largest and most sparsely populated civil parish on Exmoor, covering nearly 32 square miles (83 km2) but with a population, at the time of the 2001 census, of 203 in 78 households, reducing to 156 at the 2011 census. The River Exe rises from a valley to the north, and the River Barle runs through the village and is crossed by a triple-arched medieval bridge that was extensively repaired after floods in 1952.
