London's lively, multicultural vibe entices visitors from around the world to explore and party.
London is warmest in July and August, but in spring, parks (including of course Hyde Park with its famous Serpentine lake) are a riot of floral colour. In winter, bars and pubs are snug and welcoming. Plenty of holidays and festivals are celebrated in London all year round. Every August Bank Holiday, for example, Notting Hill Carnival comes to North West London. February sees wonderful Chinese New Year celebrations, and in April the London Marathon and the Oxford and Cambridge boat race on the Thames both take place.
London is a relatively safe city. However, watch out for pickpockets on busy trains. There is a 'congestion' charge (around £11) for motor vehicles in central London 7am-6pm from Monday to Friday. Visitors should be aware that London tends to be more expensive than other cities in the UK.
