Prices explained

At Loco2 we believe in price transparency. We use real data from Loco2 searches to estimate the cheapest fares you should be able to find for your journey.

The cheapest price is the lowest fare we've ever found for this journey. These prices can usually be found by searching when booking opens but they vary due to availability, which depends on factors like the day of the week or time of year.

More popular journeys include 30 day advance and 7 day advance prices. These are updated every two weeks using prices we've found by searching exactly 7 or 30 days from the most recent Thursday (we picked Thursday because this is when average prices are usually found).

30 day and 7 day prices fluctuate based on demand and availability at the time of search. For example, the 7-day price in summer is likely to be more expensive than the same journey in winter.

Prices are sourced in GBP and converted to other currencies using the daily market exchange rate.

We're always seeking to improve how price-checking works, and we welcome feedback on how we can make it better.

  1. It is very easy to travel by train from London to San Sebastián. By day, you can make the full journey in about nine hours.

    *** TAKE NOTE ***

    The overnight train, known as La Palombe Bleue, from Paris to Hendaye and Irun (on the French-Spanish border) was withdrawn in early July 2017. The cancellation of this train coincided with the introduction of very much faster day trains on the line from Paris to the Spanish border, thanks to the opening of a new high-speed line to Bordeaux.

    We therefore recommend that passengers travelling from London to Irun use daytime options. If you cannot find a through service to Irun, just book to Hendaye, from where it is just a few minutes on the regular tram link to Irun. Onward connections from Irun are available to San Sebastian and destinations across Spain.

    Tickets for the daytime journey generally go on sale two to three months in advance of travel. If you are keen to bag a bargain fare, it’s wise to book when tickets are first released for sale.

    London to Paris

    London to Paris

    Board a Eurostar service from London to Paris. There are upwards of 15 trains to Paris from London each day with departures at least hourly from the beautifully restored station at St Pancras in London. The fastest trains speed to Paris in just 2 hrs 16 mins, with slower services taking up to 20 mins longer to reach the Gare du Nord in Paris. The first part of the journey from London sweeps through Thameside landscapes and rural Kent to reach the Channel Tunnel. Little more than an hour after leaving London you'll already be in northern France, tracking south through Flanders fields towards Paris.

    Remember to factor in at least half an hour for Eurostar's airline-style baggage check prior to boarding your train. There is a luggage and body scan and you'll be asked to show your passport. There are no restrictions on taking liquids on board Eurostar trains.

    Paris interchange

    Paris interchange: Paris Nord to Paris Austerlitz

    When you get off the train at Paris Gare du Nord, look for the Métro on the lower level, which can be accessed via stairs or lift. Follow signs to Metro line 5 and take a train in the direction of Place d'Italie. There are 9 stops between Gare du Nord and Gare d'Austerlitz, which usually takes around 30 minutes so we recommend you leave at least an hour for your transfer.

    If you arrive at Gare du Nord from London, bear in mind that you can buy Paris Métro tickets at the Eurostar terminal at St. Pancras and on board the Eurostar train. Similarly, passengers arriving at the Gare du Nord on Thalys trains from Germany, Belgium and the Netherlands can buy Métro tickets on the train (at the Thalys Bar). Although universally referred to as Métro tickets, they are in fact valid on RER trains too.

    Irun to San Sebastian

    Irun to San Sebastian

    To reach San Sebastián from Irun, take a frequent local Cercanías train on route C-1 for the 22-min journey. Both local trains and mainline trains use the same station at Irun. Don’t forget to purchase a ticket, which will cost just a couple of euros, before boarding the Cercanías train.

    Alternatively, you can take the tram to San Sebastián, which leaves from near Irun station and is operated by Metro Donostialdea. It takes 33 mins to San Sebastián. There are also fast mainline trains which operate between Irun and San Sebastián. They are, however, not very frequent so it's worth taking the Cercanías train.

  2. Travelling by train from London to San Sebastián is very simple and can be done in a day. The journey starts by taking a Eurostar to Paris, where you’ll need to change stations. You’ll arrive at the Gare du Nord and leave from Paris Montparnasse. It’s a very hassle-free journey between the two Paris stations.

    The journey from Paris to Irun is on a high-speed French TGV train. Upon arrival in Irun, take a local train (called Cercanías) for the short onward journey to San Sebastián. The fare is paid locally (just a couple of euros), so book your ticket on Loco2 just as far as Irun.

    Tickets for the entire journey (up to Irun) generally go on sale three months in advance of travel. If you are looking for a cheap ticket, it’s wise to book when they are first released for sale.

    Additional options for travellers bound for San Sebastián from London and Paris are available by booking just to Hendaye. That’s the last station in France, just on the opposite bank of the river from Irun. From Hendaye, you can take the Metro Donostialdea tram to San Sebastián.

    Paris to Irun

    The TGV high-speed train from Paris to Irun departs from Paris Montparnasse station. The journey starts with a very fast non-stop run from Paris to Bordeaux, taking little more than two hours. Thereafter the pace slows. Beyond Bordeaux the train traverses the forested landscapes of Landes, eventually reaching the Atlantic coast at Biarritz. There are occasional glimpses of the sea (to the right) in the final 20 minutes of the journey to Hendaye. The journey from Paris to Irun takes under five hours.

    After the last stop in France at Hendaye, the train crosses the border into Spain to terminate in Irun, the first station in Spain. Additional train services run from Paris to Hendaye, from where a frequent light-rail service (part of the Basque Metro Donostialdea network) makes the four-minute journey across the bridge to Irun.
