Hiking
🚆 A tunnel through the rock
Built in the 19th century, between 1845 and 1848, this tunnel was dug to accommodate the railway line connecting Basel to Karlsruhe. Its construction profoundly altered the landscape of the Istein Rock, leading to the destruction of numerous prehistoric caves and rock shelters. Despite this, the site retains significant geological and historical value.
