Patenga, Beach in Chattogram, Bangladesh

Patenga is a sea beach of the Bay of Bengal at the mouth of the Karnaphuli River, about 14 kilometres south of Chattogram. Its sand is greyish-brown and the beach is narrow. A long embankment of large, angular concrete blocks, with a concrete wall, runs along the shore to hold back erosion; green trees and low blue-roofed structures stand behind it.

A severe cyclone in 1991 caused extensive damage to the coastline, prompting the construction of protective measures. The concrete wall and stone barriers were built to prevent future erosion and storm damage.

Vendors from the city sell ice cream, soft drinks and food on the sand; the best-known dish is fried, spicy mud crab served on a small plate garnished with chopped cucumber and onion. In the evening people come to the beach to enjoy the cool air, and speedboats, sea bikes and horses are available along the shore. A Burmese market nearby is used for shopping.

Patenga lies about 14 km south of Chattogram city, near the mouth of the Karnaphuli River, with Shah Amanat International Airport and the naval base BNS Isa Khan close by. Swimming is risky along this narrow beach, so visitors stay on the sand. Concrete walls and large stone blocks line the shore against erosion, and lamps light the beach at night.

The beach sits where the Karnaphuli River meets the Bay of Bengal, creating a distinctive intersection of river and sea. Cargo vessels anchored offshore nearby reveal the port's commercial activity just beyond the shoreline.
