With its crooked medieval streets, layers of history, and atmospheric buildings, London is a true walking city often best explored on a guided tour. Tours are a great way to investigate out-of-the-way, hidden, historic, and secret districts; to get an insider’s eye on where locals like to eat, drink, and be merry; and to learn all the juicy and infamous aspects of London’s history, architecture, and inhabitants.

Boat Tours

City Cruises. In nice weather, an open top-deck ride from Westminster, the London Eye, or Tower Piers to the ancient royal romping ground of Greenwich along the Thames River is one of the best ways to get acquainted with the city. You’ll pass sights like Tower Bridge, the Tower of London, and St. Paul’s Cathedral, all with a chirpy Cockney boatman running commentary. Lunch, Afternoon Tea, and nighttime cruises are also available.

London Duck Tours. Hop aboard one of the garish yellow, vintage amphibious trucks (originally used during World War II), and get ready to sputter past a stack of sights including 10 Downing Street and Westminster Abbey. Once at the MI6 building, you’ll take like a duck to water and gently amble up the Thames to the Houses of Parliament. Other tours focus on James Bond and the D-Day Landings.

Thames RIB Experience. Make like James Bond in an exhilarating special forces–style inflatable speedboat as you whiz past the MI6 building, Shakespeare’s Globe, and Tower Bridge on a high-speed 50-minute round-trip to Canary Wharf. There are also 20-minute roller-coaster blasts to the O2 Arena in Greenwich and 75-minute round-trips from Tower Pier to the Thames Barrier.

Bus Tours

Golden Tours. Various hop-on, hop-off open-top double-decker tours with this company take in the main sites on three key loops. With 60 drop-off points and 48-hour passes, they also offer discount tickets to attractions like the Tower of London and the London Dungeon, as well as nighttime tours and free walking tours and boat rides on the Thames.

The Original London Sightseeing Tour. Like its double-decker competitors, the Original London Sightseeing Tour offers various hop-on, hop-off open-top tours of the city, but its most popular feature is its 48-hour pass that includes loops of the main historic sites, the City, Westminster, and the museum districts. They also throw in free tickets for a Thames boat cruise, plus Jack the Ripper, Changing of the Guard, and Rock ‘n’ Roll walking tours.

Top Tours & Activities in London

City Tours. The City of London City Guides offer a small program of top-quality daily walks, including an insider tour of Guildhall, Mansion House, the Bank of England, and Royal Exchange, plus others focusing on topics like the city’s gardens, Charles Dickens, and famed architect Sir Christopher Wren’s churches.

Sandemans New Europe London. It seems almost too good to be true: Sandemans offers an excellent free, two-and-a-half-hour Royal London walking tour daily, which winds from Buckingham Palace to Big Ben. Led by wisecracking actors, poets, and art historians, other paid walks include a boozy five-stop pub crawl and spooky East End’s Dark Secrets tours.

Specialty Tours

Brit Movie Tours. See the exterior of Grantham House and the spot where Branson first confesses his love for Lady Sybil on this insiders’ central London tour of Downton Abbey filming locations. Other tours focusing on James Bond, Sherlock, The Da Vinci Code, and Harry Potter filming locations, among many others, are also available.

Walking Tours

Context Travel. This company takes a high-brow approach to its intellectually curious small-group walks program, providing PhD- and MA-level scholars, authors, architects, and historians to lead walks of no more than six people. Lasting up to three hours, walks include the evolution of London theater to Charles Dickens and Victorian London.

London Food Lovers. Combine walking, talking, and eating (but not at the same time) on these fabulous multistop trails, featuring restaurants and London cultural history. There are four half-day Soho-focused food tours complete with 10 stops, as well as two shorter three-hour evening options that include five stops, like the Jack the Ripper Happy Hour tasting tour, which focuses on gin, bagels, and locally brewed craft ales.

London Walks. With London’s oldest established walking tours, there’s no need to book ahead; instead, just turn up at the meeting point at the allotted hour and pay £10 for a first-rate, guided two-hour walk with themes like Secret London, Literary London, Harry Potter film locations, Haunted London, and much more. Top crime historian and leading Ripper authority Donald Rumbelow often leads the 7:30 pm Jack the Ripper walk in Whitechapel.

Sophie Campbell. Travel journalist and former BBC Travel Show broadcaster Sophie Campbell specializes in superlong London walks. Full-day walks include Old Church Chelsea (by the river) to St. Michael’s Highgate (high on a north London hill); or Hampton Court Palace to Richmond Palace via the noble palazzi of the nontidal Thames. Half-day hikes include a forensic examination of Fleet Street journalism and James Bond’s London.
