Lago di Braies is probably one of the most well-known and the largest lakes in the Dolomites, Italy. There are usually many people during the day that wander around the lake and taking rides in the wooden boats, but when the evening comes, the boats are docked, and you can sit alone and enjoy the sunlight reflecting on the mountains.
