Seychelles has two UNESCO World Heritage sites, including the legendary Vallee de Mai, one of the world's smallest natural UNESCO World Heritage Sites, where millions of years of isolation have resulted in the evolution of many unique species found nowhere else on the planet. The Vallie de Mai, a living remnant of ancient palm forests, is the green heart of Praslin Island and home to Seychelles' largest intact forest of the endemic coco de mer palm. If you're lucky, you might even see the rare Seychelles Black Parrot.
