Yes, you can absolutely walk through Westminster, and it is widely considered the best way to see London’s most iconic landmarks. A standard walking route often begins at Westminster Station, immediately bringing you face-to-face with Big Ben and the Houses of Parliament. From there, it is a short, scenic stroll across Parliament Square to Westminster Abbey. You can continue your walk down Whitehall, passing the guarded gates of Downing Street and the Cenotaph, eventually reaching Trafalgar Square. For a more leisurely "Royal Walk," you can head from the Abbey through St. James’s Park towards Buckingham Palace. While you can walk freely along the public streets and through the parks 24/7, remember that entering the landmarks themselves, such as the Abbey or the Houses of Parliament for a tour, requires a ticket and specific security screening. In 2026, walking through this historic heart of London remains a "must-do" experience, especially during the golden hour when the Portland stone of the buildings glows against the Thames.
