Molveno Lake is the largest naturally-formed lake in the Italian Alps and lies at above 800 metres. It formed after the ice age (3000-3500 years ago) when an enormous landslide detached from the mountain above (Crona Saltere), blocking the valley.

The lakeside path offers a spectacular view of the peaks of the central chain, the most imposing in the Brenta group, and the ridge of the Paganella-Gazza-Monte Ranzo range.

The Brenta group ranges from the early Triassic to the Cretaceous (about 185 million years). The main features can be found in the rocks of the end of the Triassic, Jurassic and Cretaceous periods which bear witness to the opening up of the Lombardy basin and the evolution of the western edge of the Trento platform.
