The Seven Rila Lakes (Bulgarian: Седемте рилски езера, romanized: Sedemte rilski ezera, pronounced [sɛdɛmˈtɛ ˈriɫski ɛzɛˈra]) are a group of glacial lakes, situated in the northwestern 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.
The highest one is called Salzata ("The Tear") due to its clear waters that allow visibility in depth.
The lakes are located one above the other and are connected by small streams, which form tiny waterfalls and cascades.
[citation needed] The lakes usually freeze during October, and do not melt before June.
