The Seychelles comprise over 100 islands, some granite, others coral atolls including one of the world's largest atolls, Aldabra. The islands are rich in unique wildlife, such as the giant land tortoise, many species of birds, strange plants such as the giant Coco de Mer, and untouched forests. With the increase in the number of cruising yachts visiting the Seychelles, facilities are steadily improving. All repair services are concentrated in Victoria, where there are several boatyards with slipways. Yachts use the facilities of the Seychelles Yacht Club in Port Victoria's inner harbour. The club has a bar, restaurant and laundry.
