We recommend skyscanner to assist in booking your flights.
It is possible to jump on a train in London on a Friday evening and wake up in Bagnères de Luchon the next morning, sometimes when travelling with luggage this is a much cheaper option. Take the Eurostar from Kings Cross/St Pancras to Paris Gare du Nord, followed by a short transfer to Paris Austerlitz for an overnight sleeper train and wake up in Bagnères de Luchon the next morning.
The overnight sleeper is currently under maintenance but there is a bus service from Montrejeau (just 40 minutes away from Luchon).
From Calais, Bagnères de Luchon is right in the south west of France, about as far as you can drive in France, about 9.5 hours of driving if you use the French toll roads (a little bit pricey but very rarely any traffic at all). It is possible to divide the journey up a little by using a mixture of toll and non-toll roads, why not extend your holiday and have a cheeky overnight stop in one of France's many beautiful cities?
We can give you some advice on where to stop. Sometimes you can use supermarket loyalty schemes to save money on your ferry or eurotunnel trip.
