The thermal spring water reaches the surface at a consistent temperature of 36.5 degrees Celsius, matching human body temperature.
The water found in the gorge has been flowing for approximately 10 years deep underground before reaching the surface.
The first bathhouse at the source, Old Bad Pfäfers, was constructed in 1242 after the springs were discovered by hunters.
The gorge was formed by the erosive force of the Tamina River cutting through the limestone during the post-glacial period.
The canyon is so narrow that the sky is often visible only as a thin sliver of light from the path.
Famous historical visitors seeking cures at the site include the physician Paracelsus in the 16th century.
Taminaschlucht is a narrow limestone gorge carved by the Tamina River near Bad Ragaz, Switzerland. The site is famous for the 13th-century discovery of the Old Bad Pfäfers, where thermal waters emerge from the rock at a constant 36.5 degrees Celsius. A 450-meter-long tunnel leads visitors deep into the rock to the original source of these mineral-rich springs. The gorge walls rise up to 200 meters high, effectively blocking most direct sunlight. The area has functioned as a destination for healing and hydrotherapy for over 700 years. Modern infrastructure includes a designated footpath that allows access into the narrowest sections of the canyon. The thermal water is piped from this source down to the public baths in Bad Ragaz. It remains a rare example of a geologically active site preserved for public education and history.
The entrance of the gorge tunnel where the contrast between the dark rock and the opening provides the most depth.
Wear a waterproof jacket as the gorge environment is consistently damp with dripping water.
Bring sturdy, closed-toe walking shoes to navigate the occasionally slippery, cool surfaces inside the tunnel.
Visit on a clear day, though light levels remain low inside the narrowest canyon sections.
Attempting to walk the path without proper footwear or entering the gorge without checking local weather reports for high water warnings.
Closed during winter months due to rockfall risk and icing; typically reopens in spring.
Stay on marked paths, do not touch the fragile rock formations, and maintain a quiet voice to respect the acoustics of the gorge.
