Praslin delivers two of the world's truly unmissable natural experiences: the Vallée de Mai, a UNESCO-listed palm forest where the coco de mer grows nowhere else on earth, and Anse Lazio, a beach that appears on nearly every list of the planet's finest. The rest of the island — and the surrounding islands accessible by boat — fills in around these anchors with snorkelling, birdwatching, and the particular pleasure of a small island with nowhere to rush.
