Standing at 135 metres, The London Eye is the world's tallest observation wheel, with 40 kilometre panoramic views on a clear day. The gradual flight in one of the 32 high-tech glass capsules offers spectacular views of London & its famous landmarks such as Big Ben, Buckingham Palace, St Paul's Cathedral, Westminster Abbey & Trafalgar Square. New to the London Eye is the groundbreaking 4D film which features theatre effects such as wind, bubbles & mist. This short film takes place in County Hall & is about a girl struggling to see the landmarks of London, until she rides the London Eye. You will need to book a date for the Eye at least 24 hours in advance, time slots are available on a half hourly basis. Before boarding the London Eye you will need to exchange your voucher for London Eye tickets in the County Hall ticket office. If you would like to visit the 4D Experience before your flight, we would advise you to check in 45 minutes before your flight time, alternatively you can visit at your leisure after your flight on the London Eye.
