The Seychelles are geologically unique — the only granite islands in the world's oceans. While most tropical archipelagos are coral or volcanic, the inner Seychelles islands are ancient fragments of the supercontinent Gondwana, sculpted by 750 million years of erosion into the smooth, house-sized boulders that frame the beaches of Anse Source d'Argent and Anse Lazio.
The archipelago comprises 115 islands spread across the western Indian Ocean. The inner granite islands (Mahé, Praslin, La Digue, Silhouette, and surrounding islets) are where most charters operate. The outer coral islands (Aldabra, Desroches, Alphonse) are remote and expedition-grade.
Praslin is home to the Vallée de Mai, a UNESCO World Heritage Site where the coco de mer palm — with the world's largest seed — grows wild in a prehistoric forest. La Digue has Anse Source d'Argent, arguably the most photographed beach on Earth. Curieuse Island has wild giant Aldabra tortoises. The snorkelling and diving are outstanding, with granite reef formations unlike anything in the Caribbean or Pacific.
The sailing season is year-round, though the calmer inter-monsoon periods (April and October–November) are optimal. Charterers base from Victoria, Mahé, or Eden Island Marina.
