Geopark - St. John's Mine.

St. John’s Mine is part of the Geopark and is located in the village of Krobica, just a few kilometers from Świeradów-Zdrój. It is the first stop on the open tourist trail, which showcases the rich history of mining in the Jizera Mountains.

A tour of the 350-meter-long underground route, leading through the St. John and Leopold adits, usually takes about 45–60 minutes. During the tourist season, guided tours depart every 30 minutes, while during the off-season, they depart on the hour.

The mine was a site for the extraction of tin ore (cassiterite). During the tour, the guide explains the history of tin mining, describes the hardships of the miners’ lives, and demonstrates the mining techniques used in the Jizera Mountains since the 16th century.

Yes, for safety reasons, St. John’s Mine welcomes children who are at least 6 years old. The tour route passes through authentic mining tunnels, so adhering to this age limit is essential to ensure the safety of our youngest visitors.

The underground tunnels maintain a constant, low temperature (approx. 7–8°C) and high humidity year-round. Even if it’s hot outside, it’s a good idea to bring a warmer sweatshirt or jacket and comfortable, closed-toe shoes for the tour.

The site is open to visitors almost year-round—the mine can be visited 364 days a year (usually excluding Christmas Day). Standard opening hours are 10:00 a.m.–4:00 p.m., and during peak tourist seasons, these hours are extended until 6:00 p.m.
