The mountain lakes in Northern Italy’s Dolomites region are a thing to behold. The ice-cold glacial lakes, crystal clear mountain lakes, and refreshing bathing lakes are all filled with some of the cleanest water around. In this drone video by Alberto Aedit, you'll see a small, heart-shaped lake called Coldai. It's nestled in the rocky edges at 2.1k meters (around 7k ft.) in the province of Belluno. The 4K film explores the lake and takes multiple vantage points of the surrounding mountains.
