The North Hungarian Mountains lie north of Budapest and run in a northeasterly direction south of the border with Slovakia. The higher ridges, which are mostly forested, have rich coal and iron deposits. Minerals are a major resource of the area and have long been the basis of the industrial economies of cities in the region. Viticulture is also important, producing the famous Tokaji wine. The highest peak of it is the Kékes, located in the Mátra mountain range.
