The United Kingdom is much more than London, though London alone is worth the trip. The British Museum, Borough Market, and the West End cover the classics, but the real London is in its neighbourhoods: Bermondsey, Hackney, Peckham, Marylebone. Each has its own food scene, pub culture, and character that the tourist trail largely misses.
Beyond the capital: Edinburgh's stone city and castle rock, the Lake District's rolling fells, Cornwall's dramatic Atlantic coastline, and Scotland, which deserves its own trip entirely.
