Chiltern Hills near Nettlebed

The Chiltern Hills span the area between Wessex in the South West and Hitchin in Hertfordshire - across much of Buckinghamshire and Bedfordshire. These rolling hills feature swathes of habitat-rich grassland, broken up by ancient beech, ash and box woodland.

Just a short hop from London by train or in the car, this landscape is popular with ramblers and cyclists, while foodies can discover historic market towns.

History

According to the British Geological Survey, the Chilterns are part of a large geological formation which spans the area between the English Channel and Norfolk. They started forming around 145 million years ago.

Humans started living in the hills between 11,700 to 4,000 BC (Mesolithic), the hills' authority has said, when nomadic hunter-gatherers started to catch and eat red deer and fish. There is also evidence of Neolithic (4,000-2,000 BC) life in the Chilterns. with a barrow or burial mound at Whiteleaf Hill. Paths like the Icknield Way were trodden as early as 650 BC, during the iron age.

Over more recent centuries, patchwork fields, woodland and farmland developed, which became an important source of food under the Tudors (1485-1603 AD).

When the industrial revolution rolled around, the Grand Union Canal cut through the Bulbourne Valley in the late-1700s - between London and Birmingham. There are canal-side stops in and around the Chilterns, at Hemel Hempstead, Berkhamsted, Tring, Aylesbury and Cheddington.

Railways arrived in the mid-1800s, bringing towns like Reading and Amersham well into London's sphere of influence.

In 1965, the Chilterns became an Area of Outstanding Natural Beauty (AONB) to formally recognise its unique landscape and wildlife. The Chilterns Conservation Board is responsible for conservation and improvements in the AONB with the National Trust responsible for looking after some of the estates and parkland.

Landscape

Towns and villages lie low, at the bottom of gentle hills and escarpments - with ridgeway walks.

Flora and fauna

There are large beechwoods with mature trees, some more than 40m tall. Wild box and juniper also grow in the hills.

Look out for otter, water voles, brown trout and the Adonis blue butterfly which are native to the Chilterns.
