Rauchberg, Mountain summit in northern Bohemia, Czech Republic

Rauchberg, also called Dymník, is a 517 m forested basalt hill in the Šluknovská pahorkatina, 2 km southwest of Rumburk. Its summit is a volcanic vein tilted north-northwest that broke through older granodiorite, with rock outcrops showing slabby and faint columnar jointing; cliffs of olivine basalt up to 20 m high stand at its foot.

In the Middle Ages signal fires were lit on the summit, which gave the hill its Czech name Dymník, from dým, smoke. In 1895 the Gebirgsverein für das nördlichste Böhmen turned an Umgebindehaus below the hill into a mountain inn, and in 1896 councillor August Wenschuh funded a 15-metre brick lookout tower there for his 60th birthday.

The name Dymník comes from the signal fires lit on the hill in the Middle Ages, and Rauchberg means smoke mountain. Since 1895 a Umgebindehaus below the summit has served as a mountain inn, still a starting point for walks and one of the few such houses in northern Bohemia.

The routes to the summit vary in difficulty depending on which path you take. Proper footwear is helpful since the terrain is hilly and can be uneven in places.

A stone circle of 22 granite obelisks set into the ground lies on the mountain, and a rope climbing park opened near the tower in 2010. Two protected beeches, the Buky na Dymníku, grow less than 200 metres north of the summit.
