Karkonosze

On both sides of the border, large areas of the mountains are designated national parks (Krkonoše National Park in the Czech Republic and Karkonosze National Park in Poland), and these together comprise the Krkonoše/Karkonosze Transboundary Biosphere Reserve under the UNESCO Man and the Biosphere Programme. The source of the River Elbe is within the Giant Mountains. The range has a number of major ski resorts, and is a popular destination for tourists engaging in downhill and cross-country skiing, hiking, cycling and other activities.
