Low cost summer seats to mainland Europe starting at £29 are being offered by Eurostar for a limited time.
Bookings must be made by June 27 for travel between July 30 and October 16.
The one-way rates lead in at £29 to Paris, Brussels and Lille and £35 to Rotterdam and Amsterdam.
Tickets in the Standard Premier class offering more space and a meal service start at £70 each way to France and Belgium and £79 to the two Dutch cities.
A spokesman for the high speed Channel Tunnel passenger rail service said: “The great value fares provide the perfect excuse to plan a summer escape without breaking the bank and saving the time and money of travelling to an airport.”
