Encyclopedic overview
The Chiltern Hills or the Chilterns are a chalk escarpment in southern England to the north-west of London, covering 660 mi (1,700 km) across Oxfordshire, Buckinghamshire, Hertfordshire and Bedfordshire. The hills stretch 45 miles (72 km) from Goring-on-Thames in the south-west to Hitchin in the north-east, and are 12 miles (19 km) at their widest.
In 1964, 322 mi (830 km) - almost half of the Chiltern Hills - were designated by the Countryside Commission as an Area of Outstanding Natural Beauty (AONB) under the powers established by the National Parks and Access to the Countryside Act 1949.
