Want to explore the UK’s vibrant capital? You’re in luck—less than 2.5 hours from Paris, London remains the easiest major capital to reach by train from France, especially thanks to the famous Channel Tunnel! No airport transfers, no endless security checks, and you arrive right in the heart of the city. Here’s our guide to enjoying a 100% train-based city trip where culture, cuisine, and heritage come together—all without a plane or a car.
From Paris Gare du Nord, the Eurostar It runs directly from London St. Pancras International in about 2 hours and 15 minutes to 2 hours and 30 minutes, with no stops along the way, and offers nearly 15 departures a day.
Thanks to the time difference, the outbound flight seems to go by even faster: when you leave Paris at 9 a.m., you arrive in London at 10:19 a.m. local time. On the return trip, however, that same time difference works in the opposite direction.
Be sure to follow the formalities: A passport and an Electronic Travel Authorization (ETA) have been required for French citizens since Brexit, and passport control takes place before boarding, in Paris. It's best to arrive at least one hour before the train departs.
From other cities in France, the Eurostar also serves London from Lille Europe, a particularly fast route for residents of northern France.
Once you arrive at St. Pancras, the King's Cross St. Pancras subway station—located directly beneath the train station—serves six lines and allows you to reach any central neighborhood in 15 to 20 minutes.
In London, there's no shortage of possibilities: between the iconic monuments of Westminster and the creative energy of Camden Market Each neighborhood has its own unique atmosphere. Visit British Museum offers a journey through history, while the Tower Bridge offers a breathtaking panorama of the River Thames. The culinary scene, from traditional fish-and-chips to trendy brunches, invites itself into every corner. All this is easily discovered on foot or by tube, at the pace of an effervescent capital.
