Standing 135m high in a fairly flat city, the London Eye is the world’s largest cantilevered observation wheel and affords views 25 miles in every direction (as far as Windsor Castle), weather permitting. Each ride – or 'flight' – takes a gracefully slow 30 minutes. The London Eye is the focal point of the capital's midnight New Year's Eve fireworks display and one of the UK's most popular tourist attractions; book tickets online in advance for a slight discount or fast-track entry to jump the queue.
