The arrowhead-shaped country of India is bordered by the Bay of Bengal on the east coast and the Arabian Sea on the West. Climate varies from tropical at the southern tip around the Gulf of Mannar to semi-tropical on the far northeast and west borders of Pakistan and Bangladesh. Large resort on the coast such as in Goa, offers dives as part of their facilities and small dive operators and clubs can be found in other coastal town and cities.
India does not have the prolific marine life nor the diversity found in the nearby East Indies. It does however have extensive reef systems that are home to many species and some of them are only found off the Indian coast, including moray eels, rays such as the enormous Manta and Mobula ray, reef sharks, schooling fish and colourful reef fish.

The nearby Lakswadweep Islands are famous for their pure white sandy beaches, schattered idyllic islands and clear water tropical diving with shark dives and reef walls. Flights to Agatti Island depart from Cochin and Goa. However the prime dive areas in all of India are in the Nicobar and Andaman Islands. Commercial fishing is almost non-existent in the island groups so large pelagic species are abundant. Spectacular diving of International standards can be found in all areas of these island group, but access is limited, with the best opportunities through the liveboard dive vessel departing from Thailand such as the Fantasea and Gaea. Visitors can also flying into Port Blair from most mainland cities in India.
