Start your honeymoon with a romantic stroll along the Marina Beach, one of the longest urban beaches in the world. Take in the stunning views of the Bay of Bengal, watch the fishermen's boats come in with the catch of the day and admire the colonial architecture of the surrounding buildings.
Take a taxi to the Kapaleeshwarar Temple, a stunning example of Dravidian architecture built in the 7th century. This ancient temple is dedicated to Lord Shiva and is adorned with intricate carvings and sculptures that tell the stories of Hindu mythology.
For a glimpse into the cultural heritage of South India, visit Dakshinachitra, a living museum that showcases the art, craft and architecture of the region. Take a guided tour, watch local artisans at work and shop for souvenirs to take back home.
Take a day trip to the UNESCO World Heritage site of Mahabalipuram, located on the East Coast Road. This ancient port city was a thriving centre of trade and commerce in the 7th century and is home to impressive rock-cut temples, monolithic structures and cave temples. Don't miss the famous Shore Temple, a stunning example of Pallava architecture that offers panoramic views of the Bay of Bengal.
End your honeymoon with a visit to the Alamparai Fort, a lesser-known but equally fascinating historical site on the East Coast Road. The fort was built in the late 17th century by the Nawab of Arcot to protect the trading interests of the East India Company. Today, it is in ruins, but offers a glimpse into the region's colonial past.
If you have more time, you can explore other historical and cultural sites in and around Chennai, such as the Government Museum, Fort St. George and the Valluvar Kottam monument. If you have less time, you can skip Alamparai Fort and spend more time at Mahabalipuram or Dakshinachitra. Don't forget to carry sunscreen, water and comfortable footwear.
