Lake Tenno is the cleanest freshwater lake in Italy…

...a fact, which has been confirmed by a study carried out by the Fondazione Agnelli. Lake Tenno is indeed a true natural gem in Trentino and owes its nickname "lago Azzurro" (light blue lake) to its stunning shades of turquoise and light blue. Embedded in an amazing alpine landscape at an altitude of 570 m a.s.l. at the foot of Monte Misone, it is a perfectly round shaped body of water.
Lake Tenno extends over a surface of 0.22 sq km and is characterised by strong water-level fluctuations. By the end of a period of heavy rainfalls, such as in autumn, its water level is about 15m higher than in summer, when the small island in the centre of the lake can be reached on foot. In winter, this island disappears completely and only the trees are visible. Unlike the area around Lake Garda, where numerous buildings and cement paths characterise the landscape, in this isolated and peaceful spot amidst a forest you can relax and enjoy the silence. The unique setting and the white rocks on the bed of the lake give it its green and light blue colour and thus an almost tropical appearance. Lake Tenno can be reached on foot via a medieval stairway starting from the car park in its vicinity.
This quiet oasis is the perfect spot for those wanting to spend some peaceful hours in a calm and natural environment. Its extremely clean water and comfortable temperatures invite visitors for a refreshing swim. It is also possible to undertake relaxing strolls around the lake. An other spot worth visiting is the Cascata del Varone, a waterfall three kilometres as the crow flies from the lake, where the water coming from Lake Tenno plunges down almost 90 metres! Don't forget to take your raincoat with you!
In 2024 Lake Tenno was awarded the important prize "Bandiera Blu" for its excellent water quality and the particular attention dedicated to the environment and sustainable services.
