The spring forms when rainwater seeps deep underground, warms up due to geothermal heat and returns to the surface through cracks in the rock. Its temperature ranges from 18.8 to 20.8 °C, while the Tolminka has a temperature of only around 5 to 9 °C. The thermal spring is best seen when the river water level is low.
The trail is secured with railings, but includes numerous steps, ascents and descents, so suitable hiking footwear is recommended. In rainy weather, some sections may be slippery.
The circular trail is approximately 2 kilometres long and takes around 1.5 hours to complete. You can extend your visit by continuing to the Zadlaška (Dante’s) Cave, which is accessible via a marked trail, partly along a road. According to local tradition, Dante Alighieri is said to have visited the cave in the 14th century and found inspiration in its mysterious underground world for his description of Hell in the Divine Comedy.
