Seven Rila Lakes

The Seven Rila Lakes are a group of tarns—glacial lakes formed in cirques—in the northwestern part of Rila Mountain in Bulgaria. Situated between 2,100 and 2,500 metres elevation above sea level, they are the most visited group of lakes in Bulgaria. Each lake carries a name associated with its most characteristic feature. The highest one is called Salzata ("The Tear") due to its clear waters that allow visibility in depth. The next one in height carries the name Okoto ("The Eye") after its almost perfectly oval form. Okoto is the deepest cirque lake in Bulgaria, with a depth of 37.5 m. Babreka ("The Kidney") is the lake with the steepest shores of the entire group. Bliznaka ("The Twin") is the largest one by area.
