The Big Wheel
As you continue down to the River the imposing London Eye will draw you onto the South Bank. This giant wheel was built to celebrate the new millenium and a ride in one of the pods will give you unbeatable views of the Capital. At the foot of the Eye is the London Aquarium with over 12 species of shark.
If you're prepared to go even further into town, St Paul's Cathedral and the Tower of London await. You can climb up the 271 steps to the dome of St. Paul's and visit the Whispering Gallery. It's a wonderful experience. A bit further east, The Tower of London offers engrossing displays of British history, as well as the opportunity to see the Crown Jewels.
