Heathrow Airport is London's largest and busiest airport. Once you land, you'll be greeted by a sea of people and a maze of airport walkways. The biggest question you're likely to have is how you get to the city center. Heathrow Airport is a good 40-minute ride from central London, and you have three main options for transportation into it. Here's a look at the three of them and how they compare.
The Underground, also affectionately known as the Tube, is London's underground metro service. There are three underground stations that service Heathrow Airport — one between terminals 2 and 3, another in terminal 4, and another in terminal 5. At all terminals, you will pick up the Picadilly Line. You can ride this line to central London. It stops at Leicester Square, Covent Gardens, Knightsbridge, and other popular locations. Of course, you can also easily transfer to other lines once you get into the city. To use the Underground, you may want to have an Oyster Card that is loaded with cash. You swipe the card as you enter the platform to board the train.
You could also take a bus into the city. They stop at the Heathrow Central Bus Station, which is located just outside the airport between terminals 2 and 3. There are shuttles you can take from any of the terminals to the central bus station. The bus will take you straight to Victoria Coach Station. Although the bus is affordable and has more space for your luggage than the Underground, it can be a bit cumbersome to wait for the bus and access it, particularly if you flew into terminal 4 or 5.
The easiest way to get into central London is simply to take a taxi. London makes sure that all taxis entering the airport are registered, so you do not have to worry about getting scammed or ripped off. There are taxi stops at each terminal, so you do not have to walk far or wait long. You will likely pay more for a Heathrow airport taxi ride than to ride the Underground or the bus, but in return for that fee, you can be dropped directly off at your destination. Plus, there will be a driver to help you with your luggage, and you'll pay the same rate whether you have one or four people in your party.
