The lower part of the lake hides an underwater cave formed by 14 tunnels. Although it has not been investigated or explored to the end, it is currently believed to hide the longest tunnel in the world, or at least it is among the longest.


The waters of the lake come both from the sea and from thermal springs in the area. Therefore, the salinity index is not very high.
