The small town of Imotski, situated in the Dalmatian Hinterland on the northern side of Biokovo, is home to a number of interesting tourist attractions.
Two of those are the Blue and Red Lakes.
The Red Lake is a sinkhole containing a karst lake and is known for its numerous caves and remarkably high cliffs, reaching over 241 metres above normal water level and continuing below the water level.
The total explored depth of this sinkhole is approximately 530 metres making it the third largest sinkhole in the world. Water drains out of the basin through underground waterways that descend below the level of the lake floor.
The sinkhole is named after the reddish-brown color of the surrounding cliffs, colored by iron oxides.
Because of its surroundings and the depth of the sinkhole, it is very difficult to throw a stone in the Red lake, so locals have a legend that says if you can throw a stone in the Red Lake you will soon get married. Read more
