Hot Air Springs near Caldaro

This is a meteorological phenomenon where two air masses of different temperature and density meet. The warm air slides over the cold air. And warm air also flows out of the hot air springs in Caldaro all year round at a temperature of 25 degrees C. The phenomenon is only noticeable from October to April or May, because in summer and early autumn the temperatures of the environment are the same or higher than those of the hot air springs (Warmluftquellen Kaltern).

These hot air springs are rock caves at the top of the Monte di Mezzo, at the northern beginning of the Horse Teeth rock formations and south of Castelchiaro, a popular excursion destination above Lake Caldaro. As already mentioned above, at the foot of Mount Ganda in Appiano there is the opposite: the Ice Holes, from which ice-cold air (0 - 9 degrees C) emanates even in summer.

And how to reach the Hot Air Springs near Caldaro? From the Kreit district of Caldaro, just above Lake Caldaro, trail no. 13 leads to the hot air springs and the Horse Teeth rock formations in about 45 minutes. From there, the view also opens up on the South Tyrolean Bassa Atesina and Lake Caldaro. A side trip to the nearby ruins of the Castelchiaro Ruin is recommended. Also the spring hike to the Castelchiaro Fortress, a round tour of three hours, leads in this area.
