A few tips to find the lowest fares...
Thalys, Eurostar, TGV and ICE offer various fares types according to your needs, but the lowest fares are available in limited numbers.

A few tips to find the lowest fares:
Book as soon as possible:
Generally speaking, booking is possible as from 3 months ahead (4 months for Eurostar)
Avoid peak dates and times: If possible, travel on working days or at off-peak times: the cheapest fares for the weekends are sold out in no time!
