Andaman

Havelock Island

Premium scuba diving and snorkeling are the highlights of the gorgeous Havelock Island, the most popular of the Andaman Islands. Glass-bottomed boats provide a similar up-close marine life experience. Jungle treks and camping are popular landlubbing activities, though the more delicately dispositioned can choose to retire to one of several luxury resorts. Refuel with fresh coconut milk and succulent, just-caught seafood, which dominates every meal.

Neil Island

Port Blair

Floating 780 miles across the Bay of Bengal from Kolkata, this port city in the Andaman archipelago is the splash-down point for the Mahatma Gandhi National Marine Park. Diving, snorkeling and glass-bottom boat trips provide views of rare corals and marine life. On shore, family-friendly Gandhi Park offers amusement rides and a nature trail. Nearby Viper and Ross islands contain historical remnants of British rule, while Corbyn's Cove has remains of Japanese bunkers at its palm-lined beach.
