Yes, that is possible. The well-known lake in the Dolomites is accessible all year long. In winter, all those who can't get enough cold come: the ice bathers . Proper holes are sawn into the ice, where you can briefly dive into the ice-cold water. All other visitors hike along the wintry lake. We recommend that you take snow spikes with you. So you don't slip on the ice. There is no path across the lake cleared and strewn.
