Lake Bled is of mixed origins, glacial and tectonic. It came into existence after the Bohinj Glacier melted. During the last ice age the glacier deepened it's natural tectonic hollow giving it its present form, the melting ice filling the hollow.
With a surface area of 1.45 km2, it is Slovenia's most famous and most visited destination, named by Yahoo Travel as one of the World's 10 Most Beautiful Lakes and not without good reason – surrounded by mountains and with a fairytale castle perched on a crag overlooking a 17th century church on an island, it is an outstandingly beautiful place.
A popular swimming spot in summer, the lake also plays host to regular international rowing competitions including World Championships.
