Today, DOYOUSPEAKLONDON shares the perfect 3-day London itinerary, packed with unforgettable experiences and the very best of the city!

Day 1 in London: the historic heart of the city, from St Paul's Cathedral to Westminster
Your first day follows the Thames from the City of London to Westminster, taking in some of the capital's most iconic sights along the way.
Stop 1: St Paul's Cathedral & the secret Reflection Garden
⏱️ Allow 1–1.5 hours
Start your London adventure at St Paul's Cathedral, Sir Christopher Wren's masterpiece and one of the city's most iconic landmarks. Rebuilt after the Great Fire of London and famous for surviving the Blitz, its magnificent dome has dominated London's skyline for over 300 years.
Inside, don't miss the Whispering Gallery, the crypt, and the panoramic views from the Golden Gallery. Afterwards, take a moment to visit the hidden Reflection Garden behind the cathedral, one of London's most peaceful and overlooked spots.

My tip: if you plan to go inside St Paul's Cathedral, arrive at opening time for fewer crowds and some of the best views over London.
