The mine was specifically reactivated and opened to the public in 2013 to preserve local mining heritage.
The geological profile of the mine contains significant deposits of cassiterite, the primary ore for tin production.
Mining operations in this specific area were historically significant during the 16th century for cobalt, which was used as a blue pigment in glassmaking.
The underground route allows visitors to observe 'faults' and geological shifts in the rock mass that are not easily accessible elsewhere.
The temperature inside the tunnels remains around 7-8 degrees Celsius throughout the year.
The St. John Mine in Krobica is a subterranean tourist attraction featuring a 350-meter-long route through historic tin and cobalt mining tunnels. The site reveals geological structures, including visible mineralized veins of tin ore preserved within the rock walls. Visitors traverse tunnels excavated using 16th-century manual techniques and later expansion methods. Exhibits showcase the evolution of mining tools, clothing, and safety equipment. The route is situated within the Izera Mountains, a region with a deep-rooted mining history dating back to the Middle Ages. The underground environment maintains a constant year-round temperature, requiring visitors to wear warm layers. The site is managed as an educational facility focused on the history of industrial extraction in Lower Silesia.

Wear sturdy, closed-toe footwear as the path can be uneven and damp.
Even in summer, bring a jacket or fleece to comfortably manage the constant cool underground temperature.
Check the website for current group booking requirements, as some tours are only conducted with a minimum number of participants.
Do not attempt to touch the mineral veins or rock walls, as the geological formations are protected and can be fragile.
The mine is closed on Mondays; always verify seasonal operating shifts via the official website before traveling.
Safety helmets are provided by the mine and must be worn by all visitors throughout the duration of the underground tour.
