The Karl May Cave, also known as the Little Iron Cave, is located in the Waldenburg Upper Forest near Hohenstein-Ernstthal. Originally a mine tunnel dating back to 1620, it was later used as a shelter. In 1869, Karl May hid here when he was wanted for theft. Five years later, he mentioned the cave in his story "The Rose of Ernstthal." It was officially named after him in 1933. During the GDR era, it was closed to the public. Today, however, it can be easily visited again and serves as a reminder of the famous author.

Arsenic gravel of a particularly high quality was mined in the mine from the 16th century until 1846. Since 1994 the mining association Thalheim e.V. has been researching and restoring the tunnel. The mining site, known since the 16th century, was mined in the hope of finding silver ore, but without great economic success. During the Thirty Years' War, the people of Thalheim hid their few belongings in the old tunnel. Later, in the 18th and 19th centuries, arsenic gravel, nicknamed "Thalheimit", could be mined in profitable quantities. The arsenic gravel was then roasted into arsenic in the Geyer arsenic plant, the "poison smelter", and used beyond the borders of Saxony. The mine has been open to the public again since 1998 and is being saved from oblivion by the Thalheim Mining Association. Viewings are possible by prior arrangement or on fixed guided tour dates in the summer and autumn months. opening hours Viewings by prior arrangement by telephone on 03721 85157 with the Thalheim Mining Association. https://www.erzgebirge-tourismus.de/
