£1.75A double-decker bus, top deck front seat
Central LondonAn ordinary red bus is the cheapest sightseeing tour in the city. The adult pay as you go fare is £1.75, and the Hopper fare lets you change buses as often as you like within an hour for the same money.
Worth it. Take route 11 from Liverpool Street past St Paul's, Fleet Street, Trafalgar Square and Westminster, and go upstairs to the front seats. Buses take no cash, so tap a contactless card or Oyster.
