Rear cover text

The Mendip area is well known for its gorges, caves and cheese. It is a special landscape, rich in wildlife, heritage and natural resources, and owes much to its underlying geology.

The Mendip Hills have long been visited by geologists and tourists, who come to admire the spectacular rocky gorges, limestone uplands, gushing springs and subterranean streams. For those who wish to learn about the area, this guide gives details of the geology and natural history, and will help you to understand how the landscape is formed. There is something here for everyone, from the keen local walker to the tourist, the ambler and the scrambler. We hope you enjoy exploring the Mendip landscape. © NERC 2008
