Havelock Island is an ideal place in South Andaman to go diving. You can reach here from Port Blair on a catamaran ferry that takes 90 minutes or government ferries that take 2.5 hours. According to Barefoot Scuba divemaster Steve Barreto, there are 25 dive sites within Havelock. Please note that non-certified divers can only go up to 12 meters in Andaman and must be accompanied by a certified diver.
