What mountains separate Poland from the Czech Republic?

The Sudetes are a mountain range in Central Europe, also known in English (from their names in German and Czech/Polish) as the Sudeten or Sudety mountains.

The range stretches from eastern Germany along the northern border of the Czech Republic to south-western Poland. The highest peak of the range is Sněžka in the Krkonoše mountains on the Czech Republic and Poland border, which is 1,603 metres (5,259 ft) in elevation. The current geomorphological unit in the Czech part of the mountain range is Krkonošsko-jesenická subprovincie. It is separated from the Carpathian Mountains by the Moravian Gate.

The Krkonoše Mountains (also called the Giant Mountains) have experienced growing tourism for winter sports during the past ten years. Their skiing resorts are becoming a budget alternative to the Alps.
