Manombo is located as a rather small reserve in the eastern part of Madagascar, which is also commonly known as the the green belt of the island is designated. The special reserve covers an area of just over fifty square kilometers and is located south of the city of Farafangana. Manombo was established as a reserve in 1962 and is home mainly to the so-called Lowland rainforest and various wetlands. Getting to this reserve is not particularly complicated, although the area as such is divided into two parts by the national road between Farafangana and Vangaindrano.

Manombo is as a reserve especially for the numerous species of snails known to live in this part of Madagascar. In fact, no other area on the island has such a high number of snails. Around 52 different species of snails are distributed in the area of the reserve, many of which have their habitat only in this part of the island of Madagascar and are accordingly locally endemic. The attribute endemic, by the way, applies to a total of 90 percent of all animals and plants that have found their home in the Manombo. In addition to the various snails, this also includes numerous lemurs, 58 bird species, as well as ten different reptile species and some fishes. A special spectacle is offered to all visitors in October, when the Humpback whales close to the coast pass by and also the sea turtles come ashore to lay their eggs in the beach at night.
