There are plenty of wine festivals in Hungary, many of them in Budapest. But the festival held in Budafok (part of district 22) is different.
Because Budafok used to be the most important vineyard of the greater Budapest area as well as Central Hungary. Also called the wine city of Budapest. There are approximately 30-40 km of the underground passages for wine storing, not to mention it is the largest in Europe. You will find here wines from all the 22 wine-regions of Hungary.
The festival has been organized in the beginning of September for more than twenty years now. At the time of the festival the huge 100 km long underground labyrinth is open to the public. There are regular guided tours in the wine cellars, also wines can be tasted.
