Nature park Klánovice-Čihadla, Protected natural area in eastern Prague, Czech Republic.

Nature park Klánovice-Čihadla is a protected area in eastern Prague covering forests, brooks, ponds, and wetlands spread across multiple districts. Different sections are linked by marked trails that guide you through varied landscapes and habitats.

Klánovický les, also called Vidrholec, was first mentioned in the Middle Ages, when a few villages stood here and an imperial road from Prague to Moravia passed through. Poor soil and the Thirty Years' War drove villagers away during the 16th and 17th centuries, allowing dense forest to grow, which sheltered robbers including the bandit Petrovský. In 1845 the railway was completed and the first train crossed the forest; the Lichtenstein family owned most of it until 1945, when part passed to the state and part to the Klánovice municipality.

Local visitors use the different sections for walks and wildlife watching throughout the year. The paths connect forests, wetlands, and historic sites that show how nature and people coexist in this part of Prague.

You can enter the park from several points and reach it easily by public transport, particularly at Starý Hloubětín tram station or Praha-Dolní Počernice train station. The marked trails make it simple to navigate and explore different sections without getting lost.

The Klánovice forest section drains into the Vltava basin, not the Elbe, and its peaty, waterlogged soils host spiders found nowhere else in the country, including Hygrolycosa rubrofasciata and Pirata uliginosus. Two brooks, the Horoušanský and Běchovický, rise within the park.
