Regardless of where you are traveling from, your end destination for the conference will be the beautiful town of Gmunden. The town is located near the railroad that connects Vienna (Wien) to Salzburg (and Germany).
If you are traveling by train, from either Vienna (Wien) Airport or from Munich (München) Airport, your end station should be Attnang-Puchheim. On Monday late afternoon, as well as on Tuesday early morning, there will be a conference shuttle bus waiting for you at the train station. On Friday, after the conference end ceremony, there will be a shuttle service available for the return to the train station in Attnang-Puchheim.
