The Kleinenbremen Visitor Mine is a mine located in the Kleinenbremen district of the East Westphalian town of Porta Westfalica. It opened in May 1988 and is located in part of the disused Wohlverwahrt mine in the Weser Mountains. Iron ore was mined from the mine by Barbara Erzbergbau until the 1960s.

The Kleinenbremen Visitor Mine in Porta Westfalica is a fascinating destination for cyclists interested in industrial culture and geological history. In the former "Wohlverwahrt" iron ore mine, which was in operation from 1883 to 1957, visitors can now immerse themselves in the world of mining. The approximately 90-minute tours lead through underground tunnels, past original machinery, and end at the impressive "Blue Lagoon" – a subterranean lake formed by groundwater. A special experience is the ride on the mine train, which transports visitors to the various stations in the mine. The tours are led by experienced miners who provide authentic insights into everyday working life underground. In the adjoining Museum of Mining and Geological History, exhibits such as fossils, tools, and historical documents can be viewed. There are special programs for children, where they can, for example, try out a drill hammer or simulate a blasting operation.
