Izera Dark Sky Park, Dark sky reserve in Lázně Libverda, Czech Republic

Izera Dark Sky Park is a Polish-Czech cross-border dark sky park in the Izera Mountains of the Sudetes, established on 4 November 2009 and covering about 7,500 hectares. It lies half on the Czech side, from the Jizerka settlement to Smrk mountain, and half on the Polish side around the High Izera Ridge, Wielka Izerska Łąka and the Orle settlement.

The project began in 2009 through cooperation between the Astronomical Institute of the University of Wroclaw and Czech scientific institutions. This cross-border initiative was among the first of its kind in Europe and established a model for protecting night skies.

The park's Polish name, Izerski Park Ciemnego Nieba, and Czech name, Jizerská oblast tmavé oblohy, both mean the same thing: the Izera dark sky area. Public astronomy events are held here, organised with the Liberec branch of the Czech Astronomical Society, and the Polish side belongs to the Astro Izery astro-tourism project.

Bring warm clothing since nights are cool at this elevation and the best viewing period runs from autumn through spring. The access roads to various observation points vary in condition, so checking ahead about specific locations helps plan your visit effectively.

The park was the first cross-border dark sky area in the world, declared on 4 November 2009 during the International Year of Astronomy. Its roughly 7,500 hectares straddle the Polish-Czech border, half on each side of the Jizera Mountains.
