London’s many attractions have turned it into one of the world’s most visited destinations, with some 28 million visitors a year. Whether visitors are seeking culture, shopping, palaces or a great night out, London has it all. London’s easy to use public transport systems are another key to its popularity. The London Underground, known universally as “the tube”, is simple to understand while the famous red buses are a great way to get to know London at street level. For the indulgent, no visit to London is complete without a ride in a black cab, driven only by those who have completed what’s still called “The Knowledge” of all the best ways to avoid London’s traffic congestion. London’s cab drivers are among this magnificent city’s greatest characters.
