Lake Bertignano is the typical intra-morainic type, that originated from the expansions and retreats of the antique Balteo Glacier. Within the sediment accumulations deposited by the glacier remained trapped by certain water basins, among them the Bertignano one. Thanks to its location, it is less exposed to radiation, especially during the winder period when the sun is low on the horizon. The area is peaceful and easy to reach by car, even in the Winter.
Recommended period for the activity: Winter
