The Vallée de Mai Nature Reserve, located on Praslin Island in Seychelles, is a UNESCO World Heritage site renowned for its exceptional natural beauty and unique biodiversity. Situated 50 kilometers northeast of Mahé, the reserve covers an area of 19.5 hectares and is home to a primeval palm forest that has remained virtually unchanged for millions of years.


The Vallée de Mai Nature Reserve holds great historical and cultural significance. It was once believed to be the original Garden of Eden, as described in the Bible, due to the presence of the rare Coco de Mer palm tree. This palm tree, with its distinctive double coconut, was highly sought after by explorers and traders in the past, leading to the depletion of its population. In 1966, the reserve was declared a national park to protect this unique ecosystem.

Current State

Today, the Vallée de Mai Nature Reserve stands as a testament to the importance of conservation efforts. The reserve is meticulously maintained to preserve its pristine state and protect its diverse flora and fauna. Visitors can explore the reserve through well-maintained trails that wind through the dense forest, providing an immersive experience in this natural wonderland.


The Vallée de Mai Nature Reserve is home to an extraordinary array of plant species. The Coco de Mer palm, which is endemic to Seychelles, is the most iconic and dominant species in the reserve. Its enormous leaves, reaching up to six meters in length, and the largest seeds in the plant kingdom make it a truly remarkable sight. Additionally, the reserve boasts several other endemic palm species, including the Latanier Bleu and the Latanier Feuille.


The reserve is not only a haven for plants but also supports a diverse range of animal species. The Seychelles Black Parrot, one of the rarest birds in the world, finds sanctuary within the Vallée de Mai. Visitors may also spot the Seychelles Bulbul, the Blue Pigeon, and the Seychelles Sunbird, among other avian species. The reserve is also home to various reptiles, such as the Seychelles Skink and the Tiger Chameleon.

The reserve is managed by the Seychelles Islands Foundation, which ensures the protection and preservation of this unique ecosystem. Strict regulations are in place to prevent any harm to the flora and fauna, and visitors are required to follow designated paths to minimize human impact. Ongoing research and monitoring programs help to better understand and safeguard the reserve's delicate balance.
