Budapest is the closest airport to Lake Balaton. The best way to the festival site is by train, which will take about 3 hours. Take a train from the airport to Budapest Deli and then on to Zamárdi Felso station. The festival site is right next door.
Children under the age of 11 can enter the festival for free, while those under the age of 14 may enter and camp at the festival, but only with an adult.
