To escape the crowds and explore the city from a different angle, get out on the water and cruise the Thames, either by commuter service, speedboat or afternoon tea or dinner cruise. If boarding one of the five River Bus Service routes, popular landmarks along the way: the Tate Britain and Modern, SEA LIFE London Aquarium, London Eye, Shakespeare's Globe Theater, Tower of London, Tower Bridge, The O2 and Greenwich, where you'll find spectacular views and the Prime Meridian Line. Embankment Pier is quite central or click here to find your pier.
