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. Treat your senses to some of the richest South Indian flavours in traditional dishes like sambar, rasam, fish curry or kootu. And don't forget to have a cup of full-bodied Tamil coffee, enhanced with chicory—no visit is complete without it.

Blossoming bougainvilleas, crumbling cathedrals on leafy boulevards and 18th-century colonial buildings colour the former French colony of Pondy, which sits on the Bay of Bengal. But it's also unmistakably Indian, with colourful festivals throughout the year, several mosques and the Sri Aurobindo Ashram. Quiet beaches stretch north and south from town, good for swimming and sunrise strolls. Pondy is a popular weekend getaway destination from Chennai and is easy to navigate on foot or by bicycle.

A colonial touch blended with the robust Tamil culture, Pondicherry is just a two-hour picturesque drive away from Chennai. Visit here for the cobblestone cycling-friendly streets, the rich history of Sri Aurobindo and the Mother, and some of the best cafes in which to hang out. A place where lethargy is a virtue, enjoy the sun rise at the widely used beachfront. The same place converts into a local hangout at night when traffic is stopped and post-dinner walkers turn out for ice cream.

Let the beautiful coastal town of Varkala melt your worries and tensions away. Varkala’s peaceful seaside cliffs adjoin the Arabian Sea, setting the scene for several water spouts and wellness spas. The waters lapping at Papanasam beach are considered to have holy, sin-cleansing properties, and the nearby Ayurveda treatment centre will cleanse what the ocean missed.

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.

Coastal charm meets cultural heritage in the sacred city of Puri, where pilgrims flock annually to celebrate the Ratha Yatra. Besides world-famous temples, Puri boasts beaches and markets that buzz year-round, while the wetland landscape beyond the city retains its wild edge.

Mumbai (formerly known as Bombay), India, is famous for its chaotic streets. For bargains and people-watching, outdoor bazaars top the list of attractions. Popular waterfront destinations are Marine Drive, where visitors go to watch the sun set over the Arabian Sea, and the carnival-like Juhu Beach. More sightseeing options are the Gandhi Museum, in the leader's former home, and the cave temples of Elephanta Island. For tranquillity, Mumbai has many religious sites, lakes and parks.

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. Ghandi Park, Sippighat Farm and the century-old Cellular Jail (now a pilgrimage destination) provide glimpses into the past and present of these peaceful islands with a mysterious and multicultural past.

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.

Phuket offers a rainbow spectrum of spectacular holiday sights from blue lagoons and pink sunsets to orange-robed monks. Three wheeled-Tuk Tuks, taxis, buses and long tailed boats transport visitors between these marvels. Phuket's south coast offers its most popular beaches. The north is more tranquil. Koh Phi Phi, Phang Nga Bay and Patong Beach are popular spots. Diving, snorkeling, wind surfing and sailing are just a few active options. Inland, forested hills, mountains and cliffs wait to be explored.
