Lille to Rotterdam by train
Trains link Lille (France) and Rotterdam (Netherlands) through the European rail network. Most journeys take around 1h 27m including one or two connections at major hubs.
Operators on this corridor include Eurostar (ex-Thalys).
Train fares are dynamic — typical range is €25 to €71. Advance-purchase tickets (1–2 months ahead) almost always beat walk-up prices.
On routes under 600 km like this one, train often beats flight door-to-door once you factor in airport check-in and transfers.
