Lying between the river Danube (Donau) and the Czech and Austrian borders is the Bavarian Forest (Bayerischer Wald). It is part of an unspoilt, heavily forested mountain region, that also includes the Šumava (Bohemian Forest) in the Czech Republic. Within the region, there are more than 60 peaks over 1,000 m (3,280 ft), the highest of which is the Großer Arber at 1,456 m (4,777 ft). At the heart of the region is the Bavarian Forest National Park (Nationalpark Bayerischer Wald) woth an area of 24,250 ha (59,900 acre). Established in 1970, it is the oldest and largest national park in Germany. Abutting the national park and covering an area of 278,000 ha (687,000 acre) is the Bavarian Forest Natural Park (Naturpark Bayerischer Wald) and to the north of that, is the Upper Bavarian Forest Natural Park (Naturpark Oberer Bayerischer Wald). Together with the Czech Šumava National Park and the surrounding protected area, these form the largest protected forest area in Europe. The area is a nature lovers paradise, with glacial lakes, stunning mountain view points, hundreds of kilometres of hiking and cycling trails and numerous opportunities for both downhill and cross-country skiing in winter. The region is also a renowned European glass-producing area. The Crystal Road (Glasstraße) is one of the most famous holiday routes in Bavaria.
