London has a vast transportation system consisting of buses, trains, and the Tube (underground trains) that easily connect every part of the city. We recommend purchasing an Oyster Card for convenience and cost-effectiveness. The airport is located about 14 miles from the city center, but plenty of transport options are available, including the Piccadilly Line, Heathrow Express, and black cabs. Travel costs will vary depending on the mode of transport you choose to use.
If you have more time, consider taking a day trip to Windsor Castle or Stonehenge. If you have less time, prioritize visiting the Tower of London, Buckingham Palace, and the British Museum. It is also advisable to book tickets in advance, especially for popular attractions. Don't forget to wear comfortable shoes since a lot of walking is involved. Lastly, try out some traditional British food like fish and chips or a Sunday roast while exploring the city.
London has several airports, but the most popular and central ones are Heathrow Airport (LHR) and London City Airport (LCY). Heathrow is the busiest and largest airport in the UK, and it is located about 14 miles from the city center. London City Airport, on the other hand, is smaller and closer to the city center, so it offers a more convenient option for some travelers who want to avoid long commutes.
