Vlčí hora, Mountain summit in Bohemian Switzerland, Czech Republic

Wolfsberg is a mountain summit in Bohemian Switzerland that offers views across forested valleys and rock formations. The climb passes through different vegetation zones before reaching the top.

The summit is a conical hill of dark grey tephrite, a volcanic rock with columnar jointing, rising to 591 m. In 1887 the Gebirgsverein für das nördlichste Böhmen built a mountain hut on top, asking each hiker to carry one brick; a stone lookout tower followed in 1888. The hut burned down on 4 April 2023, while the tower reopened two days later.

The mountain's German name Wolfsberg refers to the wolves that once lived in the deep forests on its slopes; the village of Vlčí Hora below was founded in 1602 and first recorded in writing in 1719. The Czech name appeared on maps during the First Republic and became official after the Second World War.

Marked trails approach the summit from several directions, with parking available at the base. The terrain can be steep and slippery, especially after rain.

The summit is made of dark grey nephelinite tephrite containing magnetite, which deflects a compass needle. The rock shows columnar jointing, but the slopes below are built of two types of red Brtrníky granite, not basalt.
