This isolated island paradise offers fine beaches, turquoise seas and warm weather. As a result of their extraordinary history, the Seychelles are also rich in rare plants which flourish nowhere else on the planet. No less than 81 species are unique survivors from the luxuriant tropical forests that covered the islands until humanity's belated arrival two centuries ago. Outstanding amongst these is the coco-de-mer (sea coconut), native to Praslin, which grows in the Vallée de Mai. Its seed is the largest in nature.
