Red Lake, Karst lake in Imotski, Croatia.
Red Lake is a karst lake in Imotski surrounded by steep cliffs with reddish-brown walls. The water sits about 241 meters below the surrounding cliff edges, which form a natural amphitheater shape around the basin.
The lake formed when the ceiling of a large underground cave system collapsed, creating one of the world's largest sinkholes. This geological event shaped the landscape that draws visitors today.
Local communities have long shared stories about mysterious creatures said to inhabit the lake's depths. These tales have become woven into the region's folklore and traditions.
Visitors can follow marked trails along the lake's edge, with parking available at the main entrance. The paths offer several viewpoints where you can see the cliffs and water from different angles.
The water reaches depths of 530 meters, with its lowest point sitting about 4 meters below sea level. This makes it one of the world's deepest sinkholes and a rare geological phenomenon.
