The ice caves at Vranov nad Dyjí are located in one of the deep meanders of the river Dyje. The northern slope of the meander, under a distinct tectonic disorder manifested as a separating zone, faced the movement and dislocation of the rock masses and the formation of deep rock crevices, extensive block rubble and stone streams. A lot of pseudokarst caves were created as a result of sloping. The geomorphological situation and the convenient microclimate of the site create conditions for the occurrence of ice cave fillings and cavities in the sutures, which lasts until the late summer and also affects the local occurrence of cold-nosed species of plants and animals. Underground spaces are among the most important habitats of bats in Moravia.
