The Amirantes Group, the Alphonse Group, and the Aldabra Group all belong to the Outer Islands located in Seychelles. While Alphonse Group has some of the finest saltwater fly fishing, the Aldabra Group is the most remote. It consists of Aldabra Atoll that can be found more than 1,000 kilometers from Mahé and is a UNESCO World Heritage Site.
The Outer Islands are those situated beyond the Seychelles plateau. They comprise 72 low-lying sand cays and atolls lying anywhere between 230km and 1150km from Mahé. Less visited than their granitic cousins due to their relative remoteness, these pristine miniature worlds, some little more than sand spits or lonely rocky outcrops, offer untouched habitats for many species of wildlife. Only one island among the Outer Island groups, namely Alphonse, currently offers accommodation facilities. It boasts luxuriously appointed lodges as well as unparalleled opportunities for sailing, fishing and diving in places where few have gone before. These islands are based on five different groups of islands.
Places to visit in Outer Islands, Syechells are five different groups of islands which are Aldabra Group, Amirantes Group, Southern Coral Group, Alphonse Group, Farquhar Group. These groups have a total of 17 islands, and among them only one island offer accommodations and that is Alphonse. Alphonse, the principal island of the Alphonse Group, is a small triangular island barely 1.2km wide, sheltered by a spectacular coral reef. Located 400km southwest of Mahé, Alphonse was initially developed around the coconut industry and was also mined for guano (decomposed bird droppings). The island remains an important nesting ground for turtles and colonies of sea birds.
Aldabra Atoll is the world's second-biggest coral atoll. It is arranged in the Aldabra Group of islands in the Indian Ocean that are a piece of the Outer Islands of the Seychelles, with a separation of 1,120 km (700 mi) southwest of the capital, Victoria, on Mahé Island. The islands were at that point known to both the Persians and Arabs, from whom they got their name. Amidst the eighteenth century, the atoll turned into a reliance of the French province of Réunion, from where endeavors were made for catching the Aldabra goliath tortoises. As there are no surface freshwater sources on Aldabra, the interests of the wayfarers (no verification of any traveler's visit preceding 1742) was just to misuse the types of tortoise, turtle and angle, and not to occupy the atoll.
