The Vallée de Mai National Park is one of the best places to visit in Seychelles for nature lovers. A UNESCO World Heritage Site, on the island of Praslin, this lush palm-studded park preserves a prehistoric forest that contains at least 4,000 examples of the rare giant coco de mer fruit palm, which is endemic to the Seychelles. Before heading off on the hiking trails, one can stop by the visitor center to learn more about the park's ecology and see some of the coco de mer's seeds, which are among the largest in the world. Other plants that flourish in the park include vanilla orchids, palmiste, latanier, splayed traveler's palm, and Chinese fans. The valley is home to many species of lizards and rare birds, such as the Seychelles bulbul; fruit pigeon; and the national bird of the Seychelles, the black parrot.
