From Vienna you got southward on the A 2 motorway direction Eisenstadt / Ungarn. When you reach the traffic-junction Guntramsdorf go ahead direction Eisenstadt on the A3 and further on to the border-crossing point of Klingenbach / Sopron. On the mainroad 84 you go about 120km until you have reached the Balaton-Lake.
You can reach us from many places in Germany. Very comfortable it is to fly Ryan Air to Sarmellek Balaton Airport which is only 30 km from Balatongyörök. (Please notice that Sarmellek is only a small airport) It is more comfortable to arrive to Budapest or Vienna.
