About United Kingdom
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.
For Australians, the GBP is strong and London is expensive — accommodation in particular demands budgeting. May to September offers the best weather and the longest days. Book popular restaurants weeks in advance. The national rail network connects most of the country, making it easy to explore beyond London without renting a car.
