Travel

For all public transportation in the Netherlands, we recommend the app/website 9292.nl to plan your trip.

Trains to Groningen: We encourage participants from Europe to take the train to Groningen. For instance, it's 6 hours from Paris (1 change), 7.5 hours from London (2 changes) or 6-8 hours from Berlin (1 or 2 changes). To check times and book international trains, use NS-International.

Buses to Groningen: Groningen is served by the FlixBus network, with connections to, among others, Amsterdam, Brussels, Hamburg and Berlin.

Flying: The closest major airport is Amsterdam Airport Schiphol. To get to Groningen, take a train from Schiphol station, which is in walking distance from the baggage claim area. There is an hourly direct train to Groningen (the final stop of the train) that takes 2 hours and 12 minutes. You can book your train ticket in advance or buy a ticket directly at the station. Note that there are no seat reservations on Dutch trains.

Groningen also has an airport of its own with a small number of destinations.

Local travel: ANTS will take place at Zernike Campus. To get here by public transport, use bus lines 1, 2, 9, 15 or 171 and get off at Nijenborgh. On these busses, you check in and check out by tapping your debit card, credit card or phone etc. Busses no longer accept change and it is not possible to buy a ticket at the bus stop.

Alternatively, we very much recommend renting a bike; it's the most convenient and pleasant way to get around Groningen. Here are some places to rent bikes:

Zernike campus is about 15 minutes from most hotels, using either public transport or a bike.
