Ice caves

The South Tyrolean Wine Road
from center of

The unusual phenomenon of the ice caves between the two villages of Kaltern (Oberplanitzing/Pianizza di Sopra) and Eppan/Appiano can be explained with a simple physical principle: air streams down through cracks in the porphyry stone, creating a system of windpipes that becomes cooler as it descends. This heavier, cold air mass collects in a 5 meter high pool in the depression. This climate is ideal for plants that would normally thrive in higher alpine regions. We do recommend to make this excursion during warm summer months.
