Green Traveller's Guide to taking the train from London St Pancras International Railway Station to Nantes in the north west of France.

It is possible to travel from London to Nantes in just over 5 hours from London if you take the Eurostar from London St Pancras to Paris Gare du Nord and change to Paris Gare Montparnasse for the train to Nantes.
Nantes is the capital of the Pays de la Loire and is a fascinating historic city - it once rivalled Rennes as capital of the old Duchy province of Brittany. It is now one of the most artistically creative cities in France and has a wonderfully joined-up public transport network, including trains, trams and a comprehensive city bike hire scheme.

How to book train tickets as part of a package with accommodation
If you want someone to book the whole journey for you or combine it with staying in hotels en route, get in touch with the travel agent Byway through its page for booking enquiries.
What's the journey like?
You have to change stations in Paris from Gare du Nord to Gare Montparnasse, which can take 20-30 minutes on the Paris metro (14 stops), but we recommend you leave at least 50 minutes for the entire transfer. See our guide to How to transfer between train stations across Paris. At Gare Montparnasse, you board an intercity train to Nantes station. Remember, whenever you’re connecting trains in France, always remember to validate your onward train ticket ('compostez votre billet') at the machine on the platform before departing (these are often coloured yellow).
