Buses 760, 763, and 767 go to Etyek from Kelenföld Bus Station.
Take the M1 out of the city, and exit at Biatorbágy/Premier Outlet Center (you don’t need a motorway sticker up to this point). After that, continue on Route 1, then enter Biatorbágy and drive through it towards Etyek. Drive all the way through Etyek, and after the Etyek sign, you will find the Öreghegyi pincesor (old hill wine cellar row) to the left of the road, just below the Korda film studio. Along this row, there are several wineries: Hernyák Estate, Etyeki Kúria, and Haraszty Vallejo as well.
It is also possible to come with a bus rented for the group—we can help with the organization—or even by taxi.
