Coimbatore, the second largest city in Tamil Nadu, is often called the "Manchester of South India" due its textile industry. Visit the Dhyanalinga Temple, a unique meditation temple dedicated to Lord Shiva. Then, go to the Marudamalai Temple, a Hindu temple dedicated to Lord Murugan, where you can enjoy scenic views of the surrounding hills. End the day with a visit to the popular shopping and entertainment center Brookefields Mall.
Take a break from the city and head to the picturesque hill station of Coonoor. Visit the Sims Park, a botanical garden with over 1000 species of plants and trees, and then take a ride on the famous Nilgiri Mountain Railway, a UNESCO World Heritage Site. Finish the day at Laws Falls, a scenic waterfall located in Coonoor.
Explore the beautiful hill station of Ooty, also known as Udagamandalam. Start with a visit to the Doddabetta Peak, the highest point in the Nilgiri Hills, followed by a trip to the Government Rose Garden, the largest rose garden in India. After a relaxing boat ride at Ooty Lake, head to the Thread Garden, which features handcrafted flowers made from thread.
Travel to Kochi, a vibrant port city in Kerala. Start with a visit to Fort Kochi Beach, the perfect spot for a leisurely walk. Then, head to the St. Francis Church, the oldest European church in India, and the Dutch Palace, a historical museum featuring Kerala murals and portraits. Finally, watch a traditional Kathakali Dance performance and indulge in some mouth-watering Kerala cuisine.
If you have more time, consider visiting Munnar, a hill station known for its tea plantations and wildlife. If you have less time, skip Coimbatore and head straight to the hill stations of Coonoor and Ooty. Also, be sure to check the weather before you go, as the hill stations can get quite chilly.
