• London City (LCY) — Closest to central London, mainly business flights. DLR connects to Bank station in 22 minutes.
• Southend (SEN) — The furthest from central London but served by direct trains to Liverpool Street.

By Eurostar

The Eurostar high-speed train connects London St Pancras International with Paris (2h15), Brussels (2h), and Amsterdam (3h45). You will need your UK ETA when travelling by Eurostar as passport and ETA checks occur before boarding. UK border controls take place at the departure station in continental Europe.

By Ferry

Ferry services connect the UK with France, Netherlands, Belgium, Spain, and Ireland. Major ports near London include Dover (1.5 hours from London by train) and Harwich. Your ETA is checked at the port before departure.

Getting Around London

The Oyster Card and Contactless Payment

The easiest way to pay for public transport in London is using a contactless bank card or smartphone. Simply tap in and tap out on buses, Tubes, trains, and trams. If you prefer, you can buy an Oyster card (a rechargeable smart card) from any Tube station. Both options offer the same fares and daily price caps.

The Underground (Tube)

London’s Underground network is the oldest in the world, with 11 lines covering 272 stations. Key tips for tourists:

• The Tube runs from approximately 5:00am to midnight (later on weekends on some lines via the Night Tube).
• Zone 1 covers central London — most tourist attractions are within Zones 1-2.
• Download the TfL Go app for real-time journey planning.
• Stand on the right on escalators and let people pass on the left.

London Buses

London’s iconic red double-decker buses are both a practical transport option and a sightseeing experience. Bus travel is cheaper than the Tube and offers a great way to see the city. Bus routes 9, 11, 15, and 24 pass many major landmarks.

River Services

Thames Clippers river buses provide a scenic way to travel along the Thames between Greenwich, Canary Wharf, the City, Westminster, and beyond. Oyster cards and contactless payments are accepted.
