Bohemian Switzerland, also known as Czech Switzerland, is a picturesque region in the north-western Czech Republic. It lies on the Czech side of the Elbe Sandstone Mountains north of Děčín on both sides of the Elbe River. It extends eastward into the Lusatian Mountains and westward into the Ore Mountains. Its highest elevation is the mountain Děčínský Sněžník at 726m above sea level. It has been a protected area since 1972. The region along the right side of the Elbe became a national park on January 1, 2000, the České Švýcarsko National Park. The National Park is adjacent to the Saxon Switzerland National Park in Germany.
