The Andaman Islands form an archipelago in the Bay of Bengal between India, to the west, and Myanmar, to the north and east. Most are part of the Andaman and Nicobar Islands Union Territory of India, while a small number in the north of the archipelago, including the Coco Islands, belong to Myanmar. The Andaman Islands are home to the only known paleolithic people, the Sentinelese people, who have had no contact with any other people.
The Andaman Archipelago is an oceanic continuation of the Burmese Arakan Yoma range in the North and of the Indonesian Archipelago in the South. It has 325 islands which cover an area of 6,408 km2 (2,474 sq mi), with the Andaman Sea to the east between the islands and the coast of Burma. North Andaman Island is 285 kilometres (177 mi) south of Burma, although a few smaller Burmese islands are closer, including the three Coco Islands. The subsoil of the Andaman islands consists essentially of Late Jurassic to Early Eocene ophiolites and sedimentary rocks (argillaceous and algal limestones), deformed by numerous deep faults and thrusts with ultramafic igneous intrusions.There are at least 11 mud volcanoes on the islands. The climate is typical of tropical islands of similar latitude. It is always warm, but with sea-breezes. Rainfall is irregular, usually dry during the north-east, and very wet during the south-west, monsoons Andaman and Nicobar Islands are developing into a major tourism hub with exotic-looking beaches and pristine islands having equally exotic names, wonderful opportunities for adventure sports like snorkeling and sea-walking.

Permits are required for foreign nationals. For foreign nationals arriving by air, these are granted upon arrival at Port Blair.
