The Eurostar is an exclusive high-speed train linking Paris and London (among other cities) and is widely known for its route that takes passengers under the English Channel.
Leaving from Gare du Nord in Paris, you will go through customs in the train station, and a short two and half hours later you will arrive at St. Pancras International in London. This highly efficient route is comfortable, fast, and will leave you just steps from King's Cross, the iconic Platform 9 3/4 from Harry Potter, and with numerous options to head out and explore London.
2. Going underneath the English Channel is cool, and no question, the tunnel is an engineering marvel, but even if you capture the moment you go under there's still not much of a view.
3. Arriving at St. Pancras International you'll find yourself just steps from King's Cross and Platform 9 3/4 ... however, even if you've edited hilarious Harry Potter outtake shots of your friends at the photo-op, it will be followed with "no one can ever see these".
4. I really do like fast trains.
