Museums in London
Explore the world-renowned British Museum. There, immerse yourself in Ancient Egypt as you view the red granite statue of Amenhotep III, the “Pond in a Garden” false fresco, and the famed Rosetta Stone. See the reconstructed Nereid Monument, the Mausoleum of Halicarnassus, and sketches by da Vinci. After visiting the stegosaurus and stopping by the earthquake simulator at the Natural History Museum, go to the Victoria and Albert Museum (V&A). Marvel at the Ceramic Staircase’s beautifully painted ceiling, view hand-painted tilework, delicate embroideries, and illuminated manuscripts.

Landmarks in London
Take photos outside Buckingham Palace, experience panoramic city views from atop the London Eye, walk around the Shaftesbury Memorial Fountain at Piccadilly Circus, visit the Tower Bridge and hear Big Ben toll the hours. Then, spend the afternoon in Hyde Park horseback riding, strolling around the Rose Garden and listening to the debaters at Speakers’ Corner.

Shopping in London
Browse the trendy boutiques along King’s Road and explore London’s famed department stores. For luxury goods, visit Sloane Street and Harrods in Knightsbridge.

Getting around London
Pick up a Visitor Oyster Card and take the Tube. If you want to sightsee on the way to your next activity, hop on an iconic double-decker red bus. Rent a bicycle and use the bike lanes that run through Inner London. You can also hail one of the ubiquitous black taxis.

How to get from the airport to the city centre?

There are several options to go from Heathrow Airport to central London, from train and subway to buses and, of course, the traditional black London cabs. Travel time can range from 15min at the Heathrow Express train to over 1 hour by car/taxi, and cost you from $4 to over $70.

London Underground (Tube): Heathrow is connected with the city by tube. The Piccadilly line wraps around the airport connecting all Terminals. It runs every few minutes and will take you to any central location in under 1 hour. It is the quickest and most efficient way of getting to town.

Trains: Non-stop trains run to Paddington every 15 minutes, and the journey time is 15-20 minutes from all Terminals. Worth noting that Paddington is not in the city centre as such. You will need to take another tube ride, taxi or bus to get to the heart of London.

Taxi: There are plenty of taxis outside all terminals. They are very popular at Heathrow so we recommend you book something in advance as you may get stuck waiting for your turn. The ride to town costs £40 - £70 and could take up to 1.5 - 2 hours, depending on traffic.

Buses: The National Express Bus runs from all Heathrow terminals. Buses go to Victoria station or Hammersmith. The cost will range between £5 - £7 and take around 1 hour, depending on traffic.

We highly recommend taking the Piccadilly line tube as it will take you literally almost any place in central London.

Do I need a Visa to visit London?

You may need a visa to go to the UK to study, work, visit or join family. There are different visas depending on where you come from, why you want to come to the UK, how long you want to stay and your personal circumstances and skills. Before you apply, you must check if you need a visa and what type you need. Depending on your nationality, you might not need a visa to visit or transit through the UK. Your application must be approved before you travel. See more information on a href="https://www.gov.uk/apply-to-come-to-the-uk">applying for a visa to go to the UK.
