Begin your day by visiting the Fort St. George, a historic landmark that was once a colonial British fort. Continue to the Marina Beach which is the second-largest urban beach in the world. Visit the Kapaleeswarar Temple in Mylapore, one of the oldest temples in Chennai dedicated to the Hindu God Lord Shiva. After lunch, visit the Government Museum to learn about the history and culture of Chennai. Finally, end your day by taking a stroll at the Santhome Cathedral Basilica, a beautiful Neo-gothic Catholic Church.
Start your day early and take a scenic drive to Munnar, a hill station in the Western Ghats of South India. On your way, stop at the Valara Waterfalls, which is about 30 km from Munnar and has breathtaking views. Once you reach Munnar, visit Eravikulam National Park, a famous wildlife destination that houses the endangered Nilgiri Tahr. Next, visit the Mattupetty Dam, which is a popular picnic spot and offers panoramic views of the surrounding hills and valleys. End your day by watching the sunset at the Top Station, the highest point in Munnar with stunning views of the Western Ghats.
If you have more time, you can visit the Chennai Rail Museum or the Birla Planetarium. In Munnar, visit other points of interest such as Tea Museum or Chokramudi Peak, which are equally stunning. If you have less time, you can remove Valara Waterfalls from the itinerary.
