The "Hungarian Sea", is the people's name for the 50-mile long lake with silky green-yellow water in the middle of Transdanubia. Lake Balaton is one of Hungary's most precious treasures and most frequented resorts. It is also the largest lake in Central Europe. The southern shores are ideal for small children because of the shallow water, but on the north shore the water gets deeper instantaneously. The summer water temperature is around 80 °F, which is warmer than the average air temperature in the morning and in the evening. The water and the sleek mud of the lake are excellent remedies for nervous complaints, anaemia and nervous fatigue. Picturesque vineyards in the region produce an assortment of excellent wines that go very well with the delicious local food. Large numbers of inns and restaurants welcome guests from home and abroad.
