Eurostar is to begin trial services to Lyon and Aix-en-Provence in May and June next year as an addition to its summer services to Avignon.
Tickets for the weekly service that will run between 04 May and 29 June from London St Pancras and Ashford go on sale on 11 December.
Passengers on the return service will need to disembark in Lille for security and passport checks before transiting through the Channel Tunnel.
Eurostar commercial director Nick Mercer said: "Our direct Avignon summer services grow in popularity year on year and our customers tell us they'd like to see it extended to offer even more choice of holiday destinations.
"We're committed to listening to their feedback, which is why we're testing this new service to Lyon, Avignon and Aix-en-Provence, three of the most popular destinations in the south of France.
"By trialling this new service for future years, and by opening sales to our existing annual summer Avignon services earlier than usual, we are giving customers even more flexibility and choice when planning their trips to the south of France next year.
"Journeys with Eurostar avoid the summer scramble at the airports and we encourage passengers to book early to avoid disappointment."
