London Eye

On a clear day the London Eye, the world's largest observation wheel, offers views as far as Windsor Castle, 25 miles away. There are a number of flight options: for instance you could combine your flight with a river cruise, take a Champagne flight or book a private capsule (ring 0870 220 2223). Booking is advised but a number of tickets are held back for same-day sale on site, so it may be worth turning up and taking pot luck if you haven't booked, although weekends and school holidays tend to sell out in advance. Disabled visitors and wheelchair users should ring to pre-book a ticket. Discover Flights on the London Eye, which include a guide for those not familiar with London, are available in English, French, German, Spanish or Russian. The Afternoon Tea Capsule includes a traditional afternoon tea served during the flight (private capsule £460, plus £18 per guest, with a minimum of 20 guests).
