Lago di Tovel, also known as Lake Tovel, is a mountain lake located in the Brenta Dolomites in the Trentino-Alto Adige/Südtirol region of northern Italy. The lake is situated at an altitude of 1,178 meters above sea level and is known for its clear blue-green waters that change color throughout the day.

Lago di Tovel is surrounded by mountains and forests, making it a popular destination for hiking, trekking, and other outdoor activities. Visitors can explore the surrounding trails and enjoy stunning views of the lake and its surroundings.

The lake is also known for its wildlife, including red deer, chamois, and golden eagles. In the past, the lake was famous for the reddish color of its waters, caused by a specific type of algae. However, the algae disappeared in the 1960s due to changes in the ecosystem, and the lake's waters now have a more typical blue-green color.

Lago di Tovel is part of the Adamello Brenta Natural Park, which is home to many other natural wonders, including glaciers, waterfalls, and forests. The park is also a popular destination for skiing and other winter sports, with several ski resorts located nearby.
