Lake Tovel is the largest natural lake in Trentino and is one of the jewels of the Adamello Brenta Natural Park. It is located at the northern end of the famous Brenta Dolomites and is surrounded by the Campa massive, a majestic rocky amphitheatre which connects Passo Grostè and Passo Gaiarda. The unmistakable colour of its waters has made it famous right across the globe.
The deep blue colour of the 39 metre deep water in the middle of the lake gives way to emerald towards the shores. The contrast is even clearer when the water washes up on the brilliantly white beaches: it looks like Caribbean sand but is in fact a precious powder of Dolomite rock! Until the early 1960s, something incredible would happen in the summer months: the water would turn red due to the presence of a microscopic algae (tovellia sanguinea) which still exists but in much lower amounts.
