The summerschool will take place at the Heimvolkshochschule Lubmin. Lubmin is a small health resort situated in the Northeast of Germany at the Baltic Sea.

A wide beach is approximately 10 meters away from the Heimvolkshochschule. The Heimvolkshochschule consists of a main house with living rooms, seminar rooms, a PC room and dining rooms. Several smaller bungalows are at the area of the Heimvolkshochschule together with a fire place, table tennis plates and a volleyball field.
One of the next bigger cities is Greifswald, an old city in the Hanseatic League. Greifswald university was founded in 1456 and is one of the oldest universities in Europe.

How to get to the summerschool

From Berlin (usually the train starts in Berlin-Ostbahnhof, 2 stations by S-Bahn from Alexanderplatz) you have to go by train to Greifswald-MainStation (in German: Greifswald-Hauptbahnhof; NOT Greifswald-Süd!!!). It is possible to go from other Cities in Germany to Greifswald, but trains won't be so frequently - so Berlin is a good choice for a transfer.

From Greifswald-Hauptbahnhof we will catch you, because Lubmin is still 16km away and buses go not very frequently - if at all at the weekend. For this reason we will need your time of arrival.

Trains to Greifswald go nearly every hour from Berlin. The final destination of the train is usually Stralsund.
You can check the web for trains: http://www.bahn.de

The cheapest ticket to Greifswald from Berlin may be the so called "Ostsee-Ticket" for 39€ return. If you are more than one person travelling, the 2nd -5th person will pay only half the price. You will have to return within 9 days. Here are some specifications for the Ostseeticket (only in German):
