Havelock Island at the Andamans is the most popular spot for scuba diving. Home to one of the richest coral reef ecosystem in the world, the waters here are pristine, and teeming with diverse marine life. There are two diving operators on Havelock—Barefoot Scuba and Dive India—which provide wannabe divers with training and all the requisite equipment. Both the operators are PADI (Professional Association of Diving Instructors) certified dive centres.
