Tamina Gorge - 36.5°C, 8,000 liters per minute. Two hunters from the nearby Pfäfers Monastery discovered the healing Tamina spring in 1240. Therefore, the healing properties of Pfäfers' spring water were recognized early on. Initially, the sick bathed in rock depressions, and from 1350 onwards, in wooden bathhouses across the roaring Tamina. Access to the gorge was difficult: those who could climbed ladders. The rest abseiled into the gorge in baskets – blindfolded to combat their fear. Today, the Tamina Gorge can be explored much more comfortably. From Bad Ragaz, a leisurely one-hour hike leads to the Old Baths of Pfäfers. Halfway through, you pass under the largest arched bridge in Switzerland, the Tamina Bridge. Those who don't want to walk can take the post bus or the Rösslipost (horse-drawn carriage). The entrance to the mystical gorge is located just behind the historic building. A tunnel secures the 450-meter-long path through the rock to the spring water grotto. Here, the Tamina spring bubbles continuously from the rock, day and night, at a temperature of 36.5°C, and 8,000 liters per minute.

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.

The Tamina Gorge is located above Bad Ragaz in the northern part of the Tamina Valley in the canton of St. Gallen. Between Valens and Bonadivis, the water of the Tamina has dug itself up to 200 meters into the rock for 15,000 years. The narrowest part of the crevices is 750 meters long and 75 meters deep. It is covered at the natural bridge. In the rear part of the Tamina Gorge is the thermal spring, which has water at a temperature of 36.6 degrees. From 1350 to 1969, the thermal water was used in Bad Pfäfers, in the Valens medical clinic and in the thermal baths in Bad Ragaz to cure rheumatism, for example. The water was piped there via long pipes.
