Jelenia Góra Valley in Poland is a big valley at the Silesian northern side of the Western Sudetes and next to Kłodzko Valley the largest intermontane basin of the Sudetes. It is situated at an altitude of 250–400 meters above sea level and covers an area of 273 km2. In the 19th century, the lovely landscape attracted the Prussian high nobility, which built magnificent palaces, manors and parks. The enormous number of stately homes turned the valley into one of the most important garden landscapes in Middle Europe.

The Giant Mountains, Krkonoše, or Karkonosze, are a mountain range located in the north of the Czech Republic and the south-west of Poland, part of the Sudetes mountain system. The Czech-Polish border, which divides the historic regions of Bohemia and Silesia, runs along the main ridge. The highest peak, Sněžka, is the Czech Republic's highest natural point with an elevation of 1,603 metres (5,259 ft).
