London alone justifies a trip: the British Museum, Tate Modern, National Gallery, Tower of London, and Buckingham Palace are world-class, and most are free. Beyond the capital, Edinburgh's castle and Royal Mile, the Scottish Highlands, Cotswolds villages, and Lake District offer extraordinary variety.
Stonehenge, Bath's Roman baths, Oxford and Cambridge's university cities, Wales's Snowdonia, and Northern Ireland's Giant's Causeway round out a country of remarkable depth. Premier League football matches, West End theatre, and the pub culture are cultural experiences in themselves.
