The London Eye
A firm part of the capital's skyline, the London Eye offers one of the most peerless views of London imaginable and on clear days visitors can even make out Windsor Castle.
One of the world's largest observation wheels, it weighs some 2,100 tonnes as much as 1272 black cabs. If you really want to put on the Ritz, there are a number of themed experiences from afternoon tea to Valentine's packages and private capsules. But the classic 30-minute ride should offer sufficient kicks, reducing all London's monuments to matchsticks. One thing to note is that it is prudent to book on the website; walk ups are far more expensive, as are Fast Track tickets, which enable visitors to jump the queues.
