Start your day early with a visit to Mahabalipuram, known for its UNESCO world heritage site, the Shore Temple. Spend some time exploring the stone carvings at the Arjuna's Penance, the Pancha Rathas, and the Krishna Mandapam. Later, head to the Mahabalipuram Beach for a refreshing walk and a glimpse of the famous Five Rathas, monolithic rock-cut temples in various styles.
After lunch, head to the French Quarter of Pondicherry and begin your tour with a visit to the Pondicherry Promenade, a beautiful 1.5 km long stretch facing the Bay of Bengal, featuring French architectural landscapes and statues of prominent people. End your day with a stroll around the White Town, admiring French-style villas and boutique shops.
Drive to Auroville, an experimental town focusing on human unity and eco-friendliness. Visit the Matrimandir, a gold-clad meditation center that provides a peaceful ambiance for visitors. Spend some time exploring the village, observing organic farming, and checking out unique handicrafts and local eateries.
After lunch, stroll through a quiet and calm Serenity Beach, a popular destination for young people, particularly surfers. This is a perfect spot to chill and watch the sunset while practicing some yoga or paddling. Spend some time exploring the nearby cafes and little shops.
If you have more than 2 days, consider adding a visit to the Aurobindo Ashram, try Pondicherry's famous French cuisine or take a city walk guided tour. For a shorter trip, remove the Serenity Beach from your itinerary to cut time.
