Pondicherry, also known as Puducherry, is a union territory of India. Unlike many other parts of India, Pondicherry has a mostly flat landscape with no hills or forests. The average elevation is at sea level, and there are a number of sea inlets, called “backwaters.” The main soil types found here are red ferrallitic, black clay, and coastal alluvial. To understand the unique charm of Pondicherry, we need to explore the physical features of Pondicherry, from its sandy beaches to its serene backwaters.
It consists of four small unconnected districts, Puducherry, Karaikal, Mahe, and Yanam. Each of these districts has unique physical features and contributes to the region’s biodiversity.
