At Robečský potok
The “Peklo” alliance of municipalities was founded by the villages of Holany, Kvítkov, Provodín, Sosnová, Stvolínky and Zahrádky on May 23, 2002; in 2004 the alliance was joined by Stružnice. Since 2007, the alliance has also included as members the villages of Kozly, Horní Libchava, Horní Police, Volfartice and the town of Žandov. The headquarters of the alliance is in Sosnová, and the village mayor of Sosnová is its chairman.
The name of “Peklo” – which literally means ‘Hell’ in Czech – is derived from the traditional designation of the canyon-like valley of the Robčí Brook (Robečský potok). The territory between Karba and Robčí, in total 44 ha, was in 1967 declared the “Peklo National Nature Reserve.” During the springtime snowmelt, the Robčí Brook rises over its banks and floods the valley marshes with their remains of riparian woodland. After the water has fallen, visitors can enjoy a large number of spring snowflakes (the largest quantity of this protected flower in North Bohemia).
In addition, a great many other protected species of flora flourish here – oxlips, yellow water-lilies,... as well as fauna: research has found nearly 250 species of insects, 4 species of amphibians, 4 species of reptiles, and large numbers of birds, fishes and mammals.
Through the romantic valley of Peklo runs a marked hiking trail with instructional signposts, passing around the cliff formations, through a tunnel through the rock, and across many wooden footbridges and wooden path-decks. The trail is 4 km in length and leads from Dubice u České Lípy to the tiny settlement of Karba.
Karba, a cluster of buildings in the traditional folk style, lies at the very end of the valley, not far from the village of Zahrádky. Spanning the valley above Karba is a steel railway viaduct still in use, 209 m long and 24 m high, constructed on five sandstone arches in 1898 and ranking among the most significant industrial heritage of the region.
The area around Robečský potok is quite famous for its spring season of snowflakes. Spent a day there a few weeks ago - quite a lovely walk during a sunny spring day...
