Even to this day, Lake Tovel is famous for the red water phenomenon, unique in the world, although that does not occur any more. Until the mid-60s, in summer a special alga would come to the surface and the expanse of water would turn bright red. A number of strange stories and legends, such as the Queen Tresenga one, originated to explain this extraordinary event.

Today, Lake Tovel is one of the naturalistic gems of the Adamello - Brenta Nature Park. A visit gives the opportunity to get in full contact with nature: the nearest town, Tuenno, is 14 km away. To walk all around the lake you need about an hour and a half, and there are many other paths in the surroundings. Here, between 1999 and 2002, the brown bear was reintroduced into the environment.
