Blue Lakes

Blue Lakes comprise five karst lakes with turquoise waters located at 809 meters elevation within the Caucasus mountains. The system includes several water bodies of varying sizes set deep within this mountainous karst landscape.

These lakes formed thousands of years ago when underground limestone caverns collapsed, creating deep water-filled sinkholes across the landscape. The geological processes that created them continue to shape this area's distinctive structure today.

The main lake carries the local name Tserik-Kel, which means rotten lake in the language of residents and refers to the hydrogen sulfide smell rising from the waters. This name reflects the immediate impression visitors notice when exploring the area.

The lakes sit in mountainous terrain with variable topography, so sturdy footwear and caution on paths are necessary. Visitors should be aware that the strong hydrogen sulfide smell in some areas might affect their comfort during the visit.

The lower lake system reaches depths of 279 meters, making it one of Russia's deepest karst lakes. This extraordinary depth was scientifically confirmed only through recent expeditions and remains surprising to many visitors.
