Vallée de Mai (May Valley) is home to the rare Seychelles Black Parrot, and it contains a well preserved palm forest made up of five endemic species, one of which is the Coco de Mer (Lodoicea maldivica). Coco de Mer (sea coconut), also called double coconut or love nut, because of its unique shape exists presently only in two places, Praslin and Curieuse (both in Seychelles), with the largest intact forest of the fruit in the Vallée de Mai.

A 19th century myth claims Vallée de Mai was the exact location of the biblical Garden of Eden, and supposes the Coco de Mer to be the forbidden fruit (Coco de Mer is shaped like a woman’s pelvis and buttocks). It was designated a UNESCO World Heritage Site in 1983, and is maintained by the SIF.
