Travel information to Groningen


Groningen has a tiny airport with only one daily connection to Aberdeen. The other, more realistic options are:

  • Amsterdam airport Schiphol: many flights from around Europe and the world. There is a train to Groningen from the airport twice an hour. Travel time: 2 ½ hours.
  • Bremen airport: has become a Ryanair hub and has therefore lots of budget flights. Four times a day there is a direct bus from the airport to Groningen central train station (Check http://www.publicexpress.de/en/ for details). Travel time: 3 hours.


Groningen has every hour a train connecting it to the major cities in the Centre and West of the Netherlands. From Amsterdam airport Schiphol to Groningen there is a train every ½ hour (Typically 11 before and 19 past the hour from platform 3 in the airport; note that the latter is a direct one, whereas for the former one has to change trains in Amersfoort). Check train times on the Dutch railways website http://www.ns.nl/cs/Satellite/travellers.
