How to use public transportation in London: All you need to know as a tourist in 2026

Understanding London public transportation zones 

London’s public transport network is divided into nine fare zones, and the cost of your journey depends on which zones you travel between. The zones help determine ticket prices across the Tube, Overground, DLR, and other services, with fares generally increasing the farther you travel from the city center.

Central London is covered mostly by Zones 1–6, and the majority of the city’s main tourist attractions are located in Zones 1 and 2. Zones 7–9 are mainly suburban areas on the outskirts of London and are less frequently visited by tourists unless they are traveling farther from the center.

Public transportation options in London

London’s public transportation system combines several types of transit, including the Underground (Tube), London buses, the London Overground, the DLR, and commuter rail services, all managed under one integrated network: Transport for London (TfL). We’ll explain how each mode of transport works and when to use them during your visit.

London Underground (Tube)

The London Underground, colloquially known as “the Tube,” is London’s subway system. For locals and tourists alike, the Tube is the fastest way to get around the city, with trains arriving every 5-10 minutes. The Tube covers over 272 stations and 250 miles of track, and there are Tube stations near most of London’s top attractions, as well as airports like Heathrow. Just look for the signature Tube station logo: a red circle with “Underground” written in a blue box.

The Tube has 11 lines: Bakerloo, Central, Circle, District, Hammersmith & City, Jubilee, Metropolitan, Northern, Piccadilly, Victoria and Waterloo & City. Certain destinations are only accessible from certain lines, so it’s important to reference the London public transportation map to determine the correct line for your destination. 

The Tube runs from 5am-midnight Monday-Saturday and 7am-11pm on Sundays and holidays. On Friday and Saturday nights, the Night Tube runs 24/7 on the Central, Jubilee, Northern, Piccadilly, and Victoria lines. However, we recommend avoiding the Tube during rush hour (7:30am-8:30am and 4:30pm-7:00pm) because the cars can get very crowded, and fares are slightly higher.

Driverless DLR trains

The Docklands Light Railway (DLR) is a fully automated rail system that serves the “docklands” area southeast of central London, with 45 aboveground stations and 6 lines. DLR provides an important link to London City airport and attractions like Greenwich and Canary Wharf. While the DLR doesn’t cover all of London, it’s one of the best ways to access the docklands, providing more scenic views and less crowded trains than the Tube.

The DLR runs 5:30am-12:30am Monday-Saturday and 7:30am-11:30pm on Sunday, with trains arriving every 5-10 minutes. You can transfer from the Tube to the DLR (or vice versa) at Bank Station, Tower Hill Station, and Canary Wharf Station.

The London Overground and other rail services 

The London Overground is a light rail service that runs between London’s main rail stations (like Paddington and King’s Cross) and out into the suburbs and Hertfordshire. If you’re taking a train to the suburbs or visiting the gardens at Hampstead Heath, the Overground can be a helpful mode of transit, but for most tourists, the Tube will be more useful. 

London tourists may also find themselves using the Elizabeth Line or other National Rail service lines to access the greater London metropolitan area, like Queen Elizabeth Olympic Park, Rodford Greyhound Stadium, and Lesnes Abbey Woods.

Public buses

While public buses may not be the quickest way to get around London, they’re very cheap, with a flat rate of £1.75 (US$2.30), and the London bus network is very extensive. Many routes operate 24/7, so you don’t have to worry about being stranded late at night. Plus, the iconic double-decker buses offer a much better view than the Tube!

Buses are used extensively by London locals, with over two billion riders per year, and if you need to transfer routes, any buses you take within the first hour of paying with a contactless card or Oyster is free.

Trams

London also has a tram system, the Tramlink, that serves south London. Tramlink only has four lines and 17 miles of track, but it hits some important attractions like Wimbledon and Lloyd Park. The tram operates 5:30am-12:00am Monday-Friday, 6:00am-12:00am on Saturday, and 7:00am-12:00am on Sundays.

River Bus

The River Bus is one the most unique forms of transit in London. Uber Boat by Thames Clippers operates under a license from TfL along 24 piers on the famous Thames River, including Tower, Westminster, and Greenwich. The River Bus offers scenic views, along with a covered deck and a bar serving snacks and drinks. While it may not be the most direct mode of transport, it’s one of the most enjoyable.

London public transportation passes and payment options 

London’s public transportation network has a variety of passes and payment options. Printed tickets are still available for the Tube, DLR, Overground, and National Rail lines, but we recommend paying with Oyster card, contactless payment, or Travelcard, which are accepted across all TfL vehicles.

Oyster card 

The Oyster card is a reloadable smart card for public transport, and you can use it to tap on and off the Tube, Overground, buses, trams, DLR, Elizabeth Line, National Rail, and even the River Bus. Oyster cards cost a flat fee of £10.50 (US$14) before being loaded with fare money. 

TfL offers a tourist-specific Visitor Oyster card that you can buy online ahead of time and have shipped to your home. The Visitor Oyster card comes preloaded with fare money, and it also offers discounts on certain restaurants, sightseeing tours, and attractions like Madame Tussaud’s. If you love planning ahead, the Visitor Oyster card may be the way to go, but for most tourists, a standard Oyster card is fine.

Contactless payment (bank card or mobile pay)

You can also use contactless payment to pay for public transport in London, including debit/credit cards and smart devices. All you have to do is tap in and out at the contactless symbol, just like you would with an Oyster card. For most tourists, contactless payment is the best way to pay for public transportation in London. It saves you the hassle of buying and managing a card for a short trip.

Day travelcard 

TfL offers Day Travelcards for visitors, which work on the Tube, buses, trams, the DLR, and the Overground. These fixed-rate paper tickets allow unlimited travel within certain zones (either Zones 1-4 or Zones 1-6) for a period of one, two, or three days. A Day Travelcard is much less flexible than an Oyster card because you can only use it on the printed dates, and Travelcards cost more money during peak times.

If you’re in London for the weekend and planning to use a lot of public transportation, the Day Travelcard may save you some money. However, if you’re only going to take one ride on the Tube or you’re going to be in London for more than three days, an Oyster card or contactless payment may be more cost-effective.

Group day travelcard 

Groups of ten or more can take advantage of TfL’s Group Day Travelcard. The Group Day Travelcard works similar to the Day Travelcard, although it has two big differences: The Group Day Travelcard is only available at off-peak times, and it’s only issued for one day at a time. The Group Day Travelcard is ideal for large families or school groups but not practical for other travelers.

How to buy London public transport tickets and travel cards

You can buy London public transport tickets and travel cards directly at kiosks in most TfL stations and newsagents. If you’re a UK resident, you can create an online Oyster account and manage and pay for your transit through the app.

For tourists, Visitor Oyster cards and Day Travelcards can be bought ahead online at either TfL’s Visitor Shop or VisitBritain, the official website of the British Tourist Board. Just make sure you allow for plenty of shipping time! If you don’t want to add another thing to your London packing list, you can buy Visitor Oyster cards in person at the Tramlink Shop in Croydon, Gatwick Airport, Stansted Airport, or on board Eurostar trains.

Note: If you opt for contactless payment, you don’t need to “buy” anything. All you have to do is tap when prompted!

How much does public transportation cost in London? 

The cost of public transportation in London varies depending on the zone, time of day, and payment method. Buses and trams charge a flat rate, but the Tube, Overground, and DLR charge based on your travel zones and whether you’re traveling during peak times.

Here is a quick table to help you compare London public transportation prices:

The River Bus has its own zoning and fare system:

So, buses and trams are consistently your cheapest option, but the increased efficiency of the Tube, Overground, and DLR might be worth the extra cost. The River Bus is by far the most expensive London public transportation option, but for many tourists, the sightseeing element makes the River Bus worth at least one ride.

Daily capping

TfL offers daily fare caps, which means that if you hit the fare maximum in a twenty-hour period, the rest of your trips will be free. If you use an Oyster card or contactless payment, daily fare caps will automatically be applied to your trips.

The exact daily cap depends on the zones you travel to and your mode of transportation. Buses and trams cap at £5.25 per day (US$7), but the Tube, DLR, Overground, Elizabeth Line and National Rail daily caps are as follows:

• Zone 1: £8.90 (US$11.85)

• Zones 1-2: £8.90 (US$11.85)

• Zones 1-3: £10.50 (US$14)

• Zones 1-4: £12.80 (US$17)

• Zones 1-5: £15.30 (US$20.70)

• Zones 1-6: £16.30 (US$21.70)

Pricing for children

Children under 11 ride free on all buses and trams, and they also ride free on the Tube, DLR, Overground, and National Rail when accompanied by a fare-paying adult rider. Children 11-15 get half-price tickets if they pay with an Oyster card, but children over 16 are considered adult riders.

Pricing for seniors 

There is no discount pricing for seniors on the TfL system, unless you’re a London resident with a blue Oyster card.
