Hungerford is on the River Dun. It is the westernmost town in Berkshire, on the border with Wiltshire. It is in the North Wessex Downs Area of Outstanding Natural Beauty. The highest point in the entire South East England region is the 297 m (974 ft) summit of Walbury Hill, centred 4 miles (7 km) from the town centre. The Kennet and Avon Canal separates Hungerford from what might be described as the town's only suburb, the hamlet of Eddington.
