Perfect for a mid-November visit, as I did today. The lake is frozen and magnificent to see. It's a short drive from San Giuseppe—it took me an hour and a quarter—but there's ice in some spots, and it's quite cold, being on the dark side. But it's worth it.

A charming alpine lake with turquoise waters, nestled in a valley surrounded by hills, with a beautiful view all around. It can be reached from San Giuseppe (1h30min from signs) and from other itineraries in Valmalenco. The path from San Giuseppe has some steep and wet sections, especially during the thaw: comfortable footwear suitable for the terrain is recommended.

The route from San Giuseppe takes about 1 hour, the path is not difficult but rather steep and wet given its exposure.

Beautiful alpine lake! Its peculiar characteristic is the blue of its water!

I go through phases of loving and hating the original Molino path up the Piramidi - you should definitely try it at least once. It’s the most direct. More suitable for the uphill than the downhill!
