The modern city with a traditional soul, London is one of the most fascinating – and best-value – destinations. As with the other top-ranking European cities, there is a heady mix of old and new. The ancient Tower of London, Houses of Parliament, Buckingham Palace and other royal residences stand beside modern edifices such as City Hall, the Gherkin and Shard London Bridge. Add in the capital’s parks and masterpiece-stuffed museums and galleries (most of which are free to visit) and it’s little wonder why millions of tourists book flights to London each year.  

In 2011 all eyes were on London for the Duke and Duchess of Cambridge’s nuptials. The oohs, aahs and rousing renditions of “God Save the Queen” kicked off what is set to be an exciting couple of years for the capital. 

This year, London will host the Olympic Games, we’ll mark Charles Dickens’s 200th birthday and we’ll rejoice in Queen Elizabeth’s Diamond Jubilee with a 1,000-boat flotilla on the Thames, jolly street parties and an extra bank holiday.

London climate

July and August are usually the warmest months, however, the Great British summer has a reputation for being a washout. January is the coolest month with temperatures in the low single digits (Celsius). Spring and autumn can be very pleasant, as the temperatures are usually higher than the rest of the UK. The rain is heaviest during November when the city averages 6cm (2.5 inches). 

Getting around London

There are tons of options, the best being the Tube. London’s underground system is the fastest and easiest way to get around. Avoid rush hour though unless you like the sardine-in-a-can crush. 

London’s iconic double-decker red buses are slower, but they can be found everywhere and won’t be as crowded. Look into getting an Oyster card or Travelcard for travelling on London’s public transport – it will save you money. You can find them at tube stops or newsagents. 

Black cabs are everywhere and very comfortable, but very expensive. Minicabs are a cheaper taxi option, but you have to order them ahead of time. Watch out for illegal minicabs that trawl the theatres and nightspots. They might seem like the only late-night option, but single women or those unfamiliar with the area should and find a different way to stay safe. 

London is a big city, but many of the tourist attractions are within walking distance or along the River Thames. Take advantage of a sunny day by walking or taking a riverboat. 

Driving is not recommended, as parking is near impossible to find and a Congestion Charge will cost you extra when driving into the city’s centre Monday to Friday between 7am and 6pm. Rent a car only if you’d like to head out into the country. You will need to be over 25 and have a licence and a credit card. For more information visit www.tfl.gov.uk.

What is good to know if travelling to London?

  • Major museums and art galleries are free to visit. These include the world-renowned British Museum, Natural History and Science Museums, Victoria and Albert Museum, Imperial War Museum and National Maritime Museum. There are also smaller, quirkier museums such as The Geffrye Museum, restored 18th-century almshouses with a number of period rooms from 1600 to the present day.
  • The Changing of the Guard at Buckingham Palace is when the new guard exchanges duty with the old guard. It’s a fantastic sight. The schedule is on the official British Monarchy website (www.royal.gov.uk).
  • Hoxton is one of the coolest places in London. It was once the centre of the rag trade. Now, its large factory spaces have been transformed in to uber-cool galleries and artists’ studios.
  • The best place to get a curry is Brick Lane in East London. Jellied eels are not as popular as they once were but if you’d like to try them, the best place, bar none, is M Manze Pie and Eel Shop, the oldest pie-and-mash shop in London.
  • The London Eye, situated on the South Bank of the Thames, offers great views of London. Another vantage point is the gallery of the Monument to the Great Fire of London in the City of London. It was built between 1671 and 1677; its 311 steps leading to an observation deck beneath the shining gold “flame”.

When is the best time to fly to London?

Peak season: Most visitors arrive on flights to London between June and September. Christmas and Easter are other peak times. School holidays – half-term weeks in October, February and May – are very busy. Families flock to the museums and attractions. Shoulder season: Shoulder season is from April to May (excluding Easter) and early September to October. September/October is a great time of year to get cheaper flights and it can be the best time to visit: fewer crowds, cheaper hotel rooms, and better light for photography and bringing out the scenery. Off season: As London is a four-season destination there’s not much of an off-season. The weeks following Christmas and New Year until Easter are fairly quiet.

How popular are flights to London this year?

There has been a 238% increase in demand for London flights over the last year.

What does LHR mean?

This is defined as London Heathrow Airport (LHR). Codes like LHR are often used to just call airports uniquely. London Gatwick Airport (LGW), London Stansted Airport (STN), London City Airport (LCY), London Luton Airport (LTN), London Southend Airport (SEN) are some additional IATA codes for airports related to your trip.
