The well-maintained net of
cross-country skitracks of the
Carinthian Natural Arena encompass 300 km. There are 42 dual track cross-country ski tracks for the Classic and the Skating Style in up to 1.500 metres above the sea level with guaranteed snow. International cross-country skiing "without borders - senza confini" is the order of the day in Nassfeld, where a cross-country ski-track of 7,6 km circulates Lake Pramollo.
The tracks provided in the lake area at Lake Weissensee have been awarded with the
Carinthian Loipengütesiegel a cross-country ski-track certificate.
