The best way to travel around London is by using its excellent public transportation system via the subway (locally known as the "Tube"), bus, or rapid transit. You can use an Oyster card to save money and time, especially if planning a full day of travel. The estimated travel cost is approximately $10 CAD per person, depending on the number of rides taken and the distance traveled.
If you have more time, take a walk through Hyde Park, visit the Tower of London, or explore the National Gallery. If you have less time, visit the Tower Bridge instead of The Shard. Dress comfortably with comfortable walking shoes and appropriate clothing based on the weather forecasts for the day.
London has six international airports, with Heathrow being the largest and busiest airport by traffic. Gatwick airport is located in the city center and is the second busiest airport. Stansted, Luton, London City, and Southend airports are mainly used for budget or domestic flights.
