Guided tours are only available on certain dates or with pre-registered groups (see website). However, the restaurant and museum are always open; the restaurant in the mine is beautifully designed, with an outdoor terrace in front of the entrance.

Stations of the Cross to the Grotto, Wangs The grotto and the Stations of the Cross in Wangs are located on a section of the Pfarrer Künzle Weg in the Buchholz area. Starting from the parish church, the path leads left along Dorfstrasse uphill to the fountain with a beautiful wayside cross. Follow the green signposts of Pfarrer Künzle Weg on Fontanixstrasse. To the left, the path leads over the bridge over the "Chlibach," where the first station of the Stations of the Cross is located. Continue along the forest path to the wooden bridge, which must be crossed. The Stations of the Cross continue along the paved Buchholzstrasse to the fountain with the final station.

Grotto in Buchholz, Wangs The Wangs Mariengrotto was created on the initiative of Pastor Künzle in 1912/1913, and the bell tower was added in 1916. A cross is located on the vaulted hill in front of the tower. A Pietà (Mother of God with suffering Jesus) in the Nazarene style was placed in the grotto.

Tüfels Chuchi, Wangs Interesting cave at an uplifting power spot The Tüfels Chuchi is a geologically interesting miniature cave. Covered in moss, dripping and dispensing water, the rock opens up. Energetically speaking, the Tüfels Chuchi is a good, uplifting power spot. The name is quite intriguing, as it demonizes a healthy, strongly vibrating place, which suggests that the place was known and used very early on. Had it been more important, a forest chapel would probably greet us at this location. Important Celtic and pre-Celtic sites have often been Christianized, while less important ones have been demonized.

Lourdes Grotto, Berschis from 1921 Out of the gratitude of the population that Berschis had been spared from foot-and-mouth disease and at the suggestion of Abbot Joseph Mariétan of St. Maurice, the Lourdes Grotto in the Holy Grove was built in 1921, largely through forced labor. On the Assumption of Mary in 1921, it was ceremoniously consecrated by the Bishop of Bethlehem in front of numerous believers who had traveled from all over Sarganserland. The white Madonna, which stands above the altar, was a gift from herbalist Johann Künzle. An artfully forged grille secures the sanctuary. The well-maintained grotto, located a little off the road, invites you to pray silently. Consecration: August 15, 1921 Text / Source: Walensee pastoral unit https://www.sesowa.ch/berschis-tscherlach/kirchen-kapellen/

Restaurant Bergwerk, Gonzen / Sargans The Bergwerk restaurant is unique in design and very attractive for individual guests as well as for banquets, family celebrations or business events. A visit after a tour or guided tour of the visitor mine is also worthwhile. The location can be adapted to the size of your event thanks to the stage that can be moved on rails. Performances such as concerts or lectures are possible on the stage. The museum in the back of the restaurant cavern gives you and your guests an insight into ore mining in the Gonzen.
