Cornwall is a ceremonial county and unitary authority of Britain, UK, forming the end of the south-western promontory of Great Britain. It is bordered to the north and west by the Atlantic Sea, to the south by the English Channel, and to the east by the county of Devon, over the Stream Tamar. Cornwall's unique culture, impressive landscape and mild climate make it a popular traveler destination, despite being rather distant from the United Kingdom's main centers of population. Encircled on 3 sides by the English Channel and Celtic Sea, Cornwall has many miles of beaches and cliffs.

Other holiday maker attractions include moorland, country gardens, important and prehistoric sites and wooded valleys. Cornwall, famous for its stunning beaches, rough shore and wild moorland landscapes, is among the world's classic visitor destinations. The county is ideal for hikers, sailors, surfers, divers, sunbathers, gastronomes and newbie historians, geographers, geologists and oceanographers and, indeed, anybody looking for time out from a busy world.

Cornwall's position suggests that it has got a comparatively warm and bright climate. Spitting distance to the Atlantic Ocean ends up in Cornwall having mild, clammy westerly winds and comparatively high rainfall, though less than more north areas of the western coast of Great Britain. Cornwall's winters are mild, and frost and snow are atypical. Almost all of Cornwall enjoys more than 1,500 hours of sun annually.

The south coast, dubbed the "Cornish Riviera", is more sheltered and there are a few broad estuaries offering safe ports, for example at Falmouth and Fowey. Beaches on the south Cornish coast often are composed of rougher sand and shingle, interspersed with rocky sections of wave-cut platform. The world famous St. Michael's Mount is found towards the western end of the south coast, near to Marazion and Penzance. Cornwall's interior is composed of an approximately east-west spine of sterile and exposed upland, with a sequence of granite intrusions, for example Bodmin Moor in the east and Land's End in the west.

Between Cornwall's uplands and the coast is more fruitful, generally pastoral farmland. Close to the south coast, deep wooded valleys provide sheltered conditions for flora that like shade and a damp, mild climate.
