The Thames, world-class museums and one of the great global cities
London is one of the world's great cities — a place of extraordinary museums (nearly all free), layered history from Roman walls to modern skyscrapers, and a cultural diversity that makes it one of the most interesting places to eat, see live music and experience the breadth of contemporary art. The Thames runs through its heart, connecting riverside landmarks from the Tower of London to Greenwich. While not a beach destination, the Thames Estuary beaches at Whitstable, Margate and Broadstairs — accessible by train — offer genuine seaside character within easy reach. London's parks, from Hyde Park to Richmond, are exceptional urban green spaces.
When to go: May to September is the warmest period. June and July are generally the sunniest months.
The best months to visit London are July, August. Peak season is July with the best combination of warm temperatures and low rainfall.
