Exmoor National Park comprises 265 square miles, of which about two-thirds lie in west Somerset and the remaining third in north Devon. Its northern boundary is the Bristol Channel coast, stretching in a dramatic series of cliffs interrupted only by the Vale of Porlock, from North Hill above Minehead in the east to Little Hangman above Combe Martin in the west. This collection of walks ranges from the bare expanses of the Chains, the last real wilderness on Exmoor, to a picturesque riverside route along the Exe, from Badgworthy Water to a coastal walk taking in the spectacular Valley of the Rocks.
