Yberg, Mountain summit in Baden-Baden, Germany

The Yberg is a 520.1 m high mountain in the Northern Black Forest, about 4.4 km southwest of Baden-Baden's centre. Its summit area is made of quartz porphyry lava from the Rotliegend period, and the ruins of Yburg Castle, built in the 12th century, stand on the peak.

Yburg Castle on the summit dates from the 12th century. The name Yberg derives from the Old High German word iwa for yew, referring to yew trees once used to make crossbows and bows. Coal seams in the mountain's base were mined from 1745 until the last attempt was abandoned in 1848.

The name Yberg derives from the Old High German word iwa for yew, pointing to former yew woodland; yew wood was once used to make crossbows and bows. The summit carries the ruin of Yburg Castle, built in the 12th century, whose tower looks west over the Upper Rhine plain and the Vosges.

Several marked trails lead from Baden-Baden to the summit, with some sections climbing steeply. The hike is manageable for average hikers, and the path through the forest is easy to follow.

The summit rock is quartz porphyry from a Rotliegend volcano, its lava solidified roughly 299 to 251 million years ago, while the base of the mountain is Upper Carboniferous rock, 318 to 299 million years old. Small coal seams in that base were mined from 1745 until the last attempt was abandoned in 1848.
