Lake Balaton runs 78km along its Tihany peninsula and Badacsony wine villages, with Hévíz's thermal lake (the world's largest) and Keszthely's Festetics Palace at the western end.
Lake Balaton swimming season at peak, Tihany Lavender Festival in late June, and Badacsony wine villages at peak terrace activity. Keszthely Helikon Festival in May.
Lake warming, Badacsony cycling along the north shore at peak photogenic, and the Hévíz thermal lake comfortable at the year-round 33°C natural water temperature.
Badacsony wine harvest at peak through September, Tihany lavender beds harvested, and the Lake Balaton cycling route at autumn quiet without summer crowds.
Lake quiet with most beach businesses closed but Hévíz thermal lake's natural warmth makes year-round bathing reliable, and Keszthely's palace stays open.
