Tamina Gorge near Old Bad Pfäfers - 36.5°C, 8,000 liters per minute. Source of our thermal water The Tamina spring is not only the namesake of our thermal spa, but also the source of our healing spring water. Europe's most abundant thermal spring rises in the Tamina Gorge near Bad Ragaz and was discovered in the early Middle Ages (in 1242). Mysterious Tamina Gorge In the Tamina Gorge between Valens and the hamlet of Bonadivis, the water of the Tamina River carves its way up to 200 meters into the earth. The narrow rock crevice of the Tamina Gorge is approximately 750 meters long and 70 meters deep. Near Old Bad Pfäfers, the gorge widens, and a road now connects Old Bad Pfäfers with the town of Bad Ragaz. Deep within the mystical Tamina Gorge beats its heart: the inexhaustible spring from which healing, body-temperature thermal water has bubbled for centuries. Among others, the physician and alchemist Paracelsus praised the healing properties of the spring water in the 16th century, which is considered an acratotherm due to its low mineral content and temperature of 36.5°C.

Fantastic geological phenomenon. After a long dry spell, the water is a bit greasy from the sun cream used by the bathers. ;-)

Once you have reached the thermal spring inside the gorge, which can be admired through a display window, you have to leave the spring and can walk back through the Tamina Valley to Ragaz or take the bus. Or you can walk west around the spring gorge over the natural bridge, which is at an altitude of 820 metres, and over several wooden steps that lead to the eastern altitude of 920 metres, and hike back to Ragaz via Pfäfers.

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, for example to cure rheumatism. The water was piped there via long pipes.

The hiking bus runs from July to September, so it's best to walk up before or after, then you'll be practically alone.
