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 just over 10 hours. But many travellers prefer the overnight option which, though slower, allows you to snooze through France by night and reach the Basque region bright and early in the morning.

    The overnight train from Paris to Irun generally runs on Monday, Friday and Sunday nights throughout the year. But the days of operation do vary during holiday periods. For northbound journeys (ie. heading back towards Paris and London), the days of operation of the night train are generally the same as southbound, but again there are variations around Christmas, Easter and other holidays.

    A tea-time departure with Eurostar from London connects well with the night train from Paris. Or book an earlier Eurostar service and enjoy dinner in Paris before joining the overnight service. Upon arrival in Irun, you’ll 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 2-3 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.
