What you need to know

Planning a summer city break in Europe? NS International train tickets are worth checking out.


💰 from €18   ⏰ until 31/08
📍 NS International


You can now book tickets for June to August departures, and booking early secures better prices.


  • Early Bird Prices: For June-August trips, fares like Brussels from €18, Cologne from €20, and Paris from €35 are cheaper than booking closer to the date.
  • Mandatory Seat Reservation: From 26/06/2026 to 31/08/2026, seat reservations are mandatory during the summer holiday period, and prices increase closer to departure.
  • Popular Routes: July is peak season. Popular Friday/Sunday departures to Paris or London often sell out 4-6 weeks in advance, so booking now still offers good choices.

If travelling from other Dutch cities, you can add connecting tickets for under €9 (2nd class).
