Bled Lake is of tectonic-glacial origin and lies 475 meters above sea level. Its surface amounts to 1.45 km2 and its average annual temperature is 12°C. Due to numerous species of fish of trophy sizes, idyllic island in the middle of the lake, Bled Castle and breathtaking surroundings, the lake is considered one of the best destinations for lake fishing in Slovenia. The lake was formed after the recession of the Bohinj glacier. It is up to 2120 m long and up to 1380 m wide, its maximum depth being 30.6 m and tectonic in origin. After the last Ice Age, the Bohinj glacier deepened the natural tectonic hollow and gave into its present form. The basin was filled with water when the ice melted. The lake has no large natural tributaries; it is fed only by a few springs.
