Izera Dark Sky Park

The Jizera Dark Sky Park is a cross-border Polish-Czech dark sky conservation area, established on November 4, 2009. It was the world’s first international dark sky park. It covers approximately 75 km² of the least populated part of the Jizera Mountains and is dedicated to observing the night sky free from light pollution.

The best observation spots are Hala Izerska (on the Polish side), the village of Jizerka (on the Czech side), and Rozdroże Izerskie. On cloudless nights, you can see over 2,000 stars here, as well as a clearly visible band of the Milky Way.

Admission to the park is completely free—the park is a nature conservation area open to all tourists. The only potential costs are for lodging in mountain huts or transportation to the Hala Izerska area.

The best conditions are on cloudless nights, especially during the new moon phase (the so-called “astronomical window” around the new moon). The fall and winter seasons offer long, dark nights, while summer allows for easy access on foot or by bike.

The park’s central points—Hala Izerska and Chatka Górzystów—can be reached on foot via trails from Świeradów-Zdrój, Szklarska Poręba, Jakuszyce, or Rozdroże Izerskie. Access by car is limited for nature conservation reasons; most roads are reserved exclusively for pedestrians and cyclists.

In addition to astronomical observations, the park offers valuable ecosystems of peat bogs and Izera mountain meadows, historic mountain huts (including Chatka Górzystów and Stacja Turystyczna Orle), traces of former glassworks, and an extensive network of hiking and skiing trails.
