Blue Badge tour guides exist all over Britain. They're professionally-trained and eventually qualify at the Guild of Registered Tourist Guides. Once that's complete, they receive their blue badge so people know they're a knowledgeable tour guide whose intelligence can be trusted.

In London, one such 'blue badger' is the Telegraph newspaper columnist, Sophie Campbell. She's led tours around London's East-End area of Elephant and Castle, showing off its more unusual and secretive side, giving historical backgrounds on various locations. She highlights where Charlie Chaplin once lived and worked, where parts of the smash-hit The King's Speech was filmed, and where one of London's biggest ever riots started.

Blue Badge walking tours really are a superb way to see an area like London especially because these type of tours are so vastly different than the bog-standard 'iconic sights' tours. To find out more about Sophie's operations and to get in touch with her, click here.
