The most south-westerly county in England, Cornwall is also one of the most popular tourist destinations in the British Isles. It is filled with historical sites maintained by the National Trust and English Heritage, such as Lanhydrock House and Pendennis Castle. Guests with children can also let off steam at the Crealy Great Adventure Park or Dairyland Farm World, which both have a wealth of outdoor attractions plus big indoor play areas should the weather take a turn for the worse. The county also has some of the best gardens to visit anywhere on the British mainland due to Cornwall's mild climate, plus the internationally renowned Eden Project. Finally, Cornwall has a range of national galleries and museums, such as The Tate St Ives and the National Maritime Museum Cornwall at Falmouth. And with its coastal location, marine attractions such as the Cornwall National Seal Sanctuary at Gweek and Blue Reef Aquarium at Newquay are well worth a visit.
