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.

Please do not encourage others to camp there too. It is forbidden and nature suffers as a result. There is rubbish from campers everywhere and there are plenty of other places where you can camp, just not here! leave your tent at home or in the car.
