One of most interesting sinkholes in Maré Island is Le Bone de Léproserie. This island is rich with impressive sinkholes (see the description of another one: Trou de Bone) – from satellite images are seen some 50 large sinkholes but in reality their number is much larger.

Le Bone de Léproserie got its name from a leper colony which was located here nearby - now little remains of it. The entrance of this magnificent sinkhole is only 25 m wide. It starts as a 50 m deep well, which becomes wider with the depth. The well continues with a 40 m deep freshwater lake, which is 160 m (!) wide at its bottom.

Lake contains 350,000 m³ of water and often erroneously is considered to be the largest underground lake in the world. Many lakes in sinkholes and caves are larger, f.e. El Zacatón (Mexico) contains 9,500,000 m³ of water.
