I recently planned a trip from Madrid to London and researched the train routes—it turned out to be quite interesting, so I’d like to share my experience. While there’s no direct train service between these two cities, with proper planning, train travel can be an excellent option.
Main Route Options
Train travel from Madrid to London requires a transfer in either Paris or Brussels. The most common route is taking the Spanish high-speed train AVE from Madrid to Paris, then transferring to the Eurostar to London. The entire journey takes approximately 12-14 hours, and choosing an overnight option can save you one night’s accommodation. Another alternative is transferring via Barcelona, though this takes considerably longer.

Fares and Booking Recommendations
Prices vary significantly—here’s a reference table I’ve compiled:
| Route Segment | Average Fare | Duration |
| Madrid-Paris | €80-200 | 10 hours |
| Paris-London | €50-150 | 2.5 hours |
| Total | €130-350 | 13 hours |
Booking 2-3 months in advance can secure the best prices, especially with Eurostar’s early bird fares, which are truly great deals. Last time I booked in advance and only paid €39, but last-minute tickets can cost over €150. I recommend regularly checking Renfe and Eurostar’s official websites for promotional offers.
Transfer Time Planning
When transferring in Paris, I suggest allowing at least 3-4 hours for the connection. AVE arrives at Paris Gare de Lyon, while Eurostar departs from Gare du Nord—you’ll need to take the metro or taxi between stations, which takes about 20-30 minutes. If your London to Madrid flight schedule is flexible, you can use the transfer time to explore Paris and enjoy some French cuisine.
Practical Tips
Regarding luggage, Eurostar allows two pieces of luggage plus one hand bag, and AVE’s baggage allowance is also quite generous. However, note that Eurostar requires you to arrive 30 minutes early for security and customs procedures, similar to flying. I also recommend downloading apps like Rail Planner or Trainline to check real-time train status and platform information.
While trains aren’t as fast as planes, you can enjoy scenery from different countries along the way, and unlike Madrid to London flights, you don’t need to worry about baggage weight limits or liquid restrictions. If your budget allows, booking train tickets in advance can actually cost about the same as budget airlines, but with a much better experience. I hope this information helps those planning this route—feel free to leave comments with any questions!
