Åland is closer than you would imagine and it's easy to travel here. The shortest ferry trip from Sweden takes only two hours and you can take a ferry from Turku in Finland both morning and evening. There’s a ferry connection from Helsinki to Åland as well.
The large shipping companies offer excellent conference facilities on board. Why not gather your colleagues and take the opportunity to arrange a pre-conference during the trip to Mariehamn?
If you prefer to fly, there are several connections from both Arlanda in Sweden as well as Turku and Helsinki in Finland. We recommend booking these tickets well in advance as the number of seats on the flights is limited
