Established in 2009 and located in an almost uninhabited part of the Jizera Mountains, the Jizera Dark Sky Park (in Czech “Jizerská oblast tmavé oblohy” and in Polish “Izerski park ciemnego nieba”) is the first international dark sky park which occupies the territory of more than one state. It takes up an area of just under 75 km².



In the Czech Republic, it stretches from the Jizerka settlement and over Mount Smrk. In Poland, it continues along the High Jizera Ridge and embraces the Great Jizera Meadow and the Orle settlement. It is among the first of its kind in Europe.
