London is one of the few cities where the best things really are free: the British Museum, the National Gallery, the Natural History Museum, Tate Modern and the V&A all have no admission charge. That flips the usual city-break math — your money goes to the paid icons (Tower of London, Westminster Abbey, the London Eye) and the food, while world-class museums cost nothing.
The classic mistake is trying to cover too much ground. London is enormous — Westminster to the Tower is an hour's walk, and Greenwich or Kew are half-day trips of their own. Group your days by area instead: Westminster and the South Bank one day, Bloomsbury and Covent Garden another, the City and Tower Bridge a third. The Tube makes everything reachable, but every crossing of the city costs you 30–45 minutes.
When to visit: May, June and September are the sweet spot — long days, tolerable crowds. July and August are peak season with queues at everything ticketed; book the Tower of London and Westminster Abbey ahead. Winter is underrated: museums are quiet, theatres are in full swing, and the Christmas period (late November to early January) is genuinely atmospheric.
