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.

Sparsely-populated beaches that give way to an ocean brimming with interesting marine life and coral gardens are just one of the reasons to visit the beautiful Andaman and Nicobar Islands.

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.

The people of Tamil Nadu consider providing food to others a service to humanity. Thus the service in the state capital, Chennai, is first-rate.

Look for spicy dishes flavoured with tamarind and coconut in Kochi, and don’t be surprised if your dinner is served up on a banana leaf.

East meets West in this sun-soaked state, where Indian culture intertwines with Portuguese influences left over from a 500-year occupation. The beaches have long served as a magnet for serene hedonists. To the north, the tourist-centric scene is prevalent, with an international flair that is now skewing more hip than hippie. Travel south for stretches of unspoiled sand and an escape from large resorts. Temples, mosques and wildlife sanctuaries provide diversions from the beach.

Lonavala is one of the twin hill stations located near to each other, the other being Khandala. These hill stations are very popular getaway spots for people from Mumbai and Pune, which are very well-linked with Lonavala by road and rail. Monsoons are the best time to visit Lonavala/Khandala.

Established in the Himalaya foothills by a British Army officer in 1820, the "Queen of the Hills" stands above the rest with its deep woods, favorable climate and Doon Valley views.

For stunning natural sights, head to Gun Hill or Childer's Lodge, the two highest peaks, or the famous Kempty waterfall.
