The Levico and Caldonazzo lakes and their effluent, the Brenta mountain torrent that flows down to the Adriatic sea, influence the microclimate of this valley in which constant humidity gives the vegetation a special green colour. Valsugana, one of the most important valleys in Trentino from a historic point of view, is surrounded by the Folgaria, Lavarone, Luserna and Vezzena highlands and the southern slopes of the Lagorai mountain chain. For centuries it has been the natural exit towards the extremely important and strategic road for commercial and tourist traffic. The capital of the upper part of Valsugana is Pergine, the third largest town in Trentino, lying at the foot of a medieval castle, rich in buildings contructed during the Reinaissance period. From Pergine the road winds through Valle dei Mocheni, a green alpine corner set among the mountains with a natural and urban environment of great interest. The valley still preserves the original language and customs of the German population who settled here in the Middle Ages. A few kilometres away, Lake Caldonazzo has become a tourist resort of great importance and not anly for Valsugana. On the shores of the lake many modernly equipped campsites host tens of thousands of tourists every year, mostly Belgians and Dutch. Many hotels and apartments are also available. Similar attractions, such as sailing and windsurfing schools, exalt the tourist offer of the other nearby lake of Levico. The village, lying on the shores of the lake, has been renowned as a spa resort since the dawn of tourism and was patronised by the nobility in the late nineteenth century, as were Roncegno and Vetriolo where other sources of mineral water flowing from the Lagorai rocks boast curative proporties. Lakes and plains, but also mountains. Panarotta is a natural balcony over the whole of Valsugana, a captivating viewpoint towards the Folgaria and Lavarone highlands, Vigolana and Trento itself.
