Cornwall is a county of England in the United Kingdom, forming the tip of the south-western peninsula of Great Britain. It is bordered to the north and west by the Atlantic Ocean, to the south by the English Channel, and to the east by the county of Devon, over the River Tamar. Taken with the Isles of Scilly Cornwall has a population of 534,300. The administrative centre and only city is Truro.
The Cornish economy depends heavily on its successful tourist industry, which makes up around a quarter of the economy. Cornwall's unique culture, spectacular landscape and mild climate make it a popular tourist destination, despite being somewhat distant from the United Kingdom's main centres of population. Surrounded on three sides by the English Channel and Celtic Sea, Cornwall has many miles of beaches and cliffs. Other tourist attractions include moorland, country gardens, historic and prehistoric sites and wooded valleys. Five million tourists visit Cornwall each year, mostly drawn from within the UK. Visitors to Cornwall are served by airports at Newquay and Plymouth, whilst private jets, charters and helicopters are also served by Perranporth airfield; nightsleeper and daily rail services run between Cornwall, London and other regions of the UK.
Newquay and Porthtowan are popular destinations for surfers. In recent years, the Eden Project near St Austell has been a major financial success, drawing one in eight of Cornwall's visitors.
