From the spa town of Bad Ragaz, this route takes you straight into the Tamina Gorge. After a good hour you reach Altes Bad Pfäfers (return trip possible by bus through the gorge). Today Switzerland's oldest baroque bath house, where kings and princesses used to bathe, is an oasis of nature, culture and enjoyment with a nationwide appeal. It houses 2 museums and the Paracelsus memorial.

Not far from Altes Bad Pfäfers is the entrance to the «spring grotto». The admission fee is CHF 5 (turnstile) and is very worthwhile: The path leads 450 metres into the crag to the grotto where the hot spring water gushes from the rock. Back in Altes Bad Pfäfers the descent begins, taking you across an unmade bridge and finally out of the gorge towards Pfäfers.

The placid village is dominated by the impressive baroque monastery church and the former Benedictine abbey. Past the Wartenstein ruins, downhill along the former «Porta Romana» military and trading road, and finally along the Rhine riverbank, the circular trail takes you back to Bad Ragaz.
