Vineyards at Lake Caldaro

Lake Kaltern (Italian: Lago di Caldaro) is a lake at the junction of the Überetsch and the Unterland in South Tyrol (Italy). Lake Kaltern is one of the largest lakes in South Tyrol (although it is rather poor in terms of lakes) and is considered – along with Lake Klopein – the warmest bathing lake in the Alps. The water temperature reaches up to 28°C in summer, and the bathing season runs from May to September.The eastern and western shores are mainly developed for tourism; the southern shore is reedy. In addition to swimming, other popular sports include rowing and pedal boating, sailing, and windsurfing. The latter benefit from the prevailing mountain and valley wind circulation and the afternoon ora wind. Motorboats are not permitted. There is also a signposted and easily accessible circular hiking trail around the lake.Source:
