The best way to go to Groningen is by train. The train station has been restored, and is one of the most beautiful in the Netherlands. In the city, parking lots are scarce.
In the city, the best way to get around is by bike, which you can rent at the train station. There are also buses.
Getting by train to Groningen is probably the easiest way to go for the average traveller.
When travelling by train, one must certainly have a look at the ceiling of the trainstation in Groningen. It's one of the remarkable elements of this historic building.
The best way of transportation is cycling. The Dutch are known for their fondness of cycling. Even elderly people keep doing it!
By train is very comfortable! Groningens' beautiful railway station is near the city centre. More in my TRAVELOGUE.
