Tsimanampetsotsa National Park is an explosive set of limestone plateau, salt lake and splendid thorny forest. The lake in this protected area is exceptional because it changes color three times a day, going from white, to topaz green, then to turquoise blue depending on its lime sulfate concentration. Unfortunately, this prevents marine animals from surviving in the lake. Either way, terrestrial animals live in the park, including birds, reptiles and radiated turtles. In addition, the local flora is also impressive, with many endemic species, including magnificent baobabs. A bit of a trek, it is worthwhile to those intrepid visitors who make it there, sometimes rewarded by a rare sight of flamingoes.
