Na Čihadle, Nature reserve in Hejnice, Czech Republic.

Na Čihadle is a 4.35-hectare raised bog reserve on the main European watershed at 965–977 m, where the Černý potok and Jedlová streams rise. Its peat layer reaches 350 cm and holds 80,000 m³, dotted with peat pools (blänky), some among the largest in the Jizera Mountains.

The plateau was long used only by bird catchers, who gave the site its name, and by charcoal burners and metal prospectors. From the 16th century the Redern family promoted mining and glassmaking settlements, and in 1776 the forest office introduced clear-cutting, which by around 1800 had removed most older growth from the central mountains. The reserve was declared in 1960; a care plan followed in 1991.

The name Na Čihadle refers to a bird-catching site (čihadlo) once operated on this plateau; bird catchers were among the few people who moved here before the Middle Ages. Today the bog lies on the main European watershed: both the Černý potok and the Jedlová stream rise here, dividing the Baltic and North Sea drainage.

There are no facilities or shops at the site, so visitors should bring their own water and snacks. Sturdy footwear is important for safely navigating the paths in different weather conditions.

The reserve lies on the main European watershed: both the Černý potok flowing north and the Jedlová stream flowing south rise here, separating the Baltic and North Sea drainage basins. Some of its peat pools, called blänky, rank among the largest in the Jizera Mountains.
