Arriving at Balatonfüred station, I board a 1984 DAF bus, painted an almost audacious shade of green. It’s also home to hundreds of wineries, many of which have traditionally been difficult to access – especially without a car. The bus I’m on – the hop-on, hop-off 46° Balaton Borbusz that launched this summer – has changed all this, by taking visitors on day trips to local vineyards. Photograph: Bernadett Pogacsas-Simon/AlamyThe bus departs Balatonfüred about every two hours from 11am, with the final drop-off at 9pm and the option to visit four wineries. Our first stop is Mórocz Pince (“pince” is the Hungarian for “cellar”), reached via a moderately steep, rocky path from the main road.
