The island offers panoramic scenic beauty and is covered by a range of low hills, about 300 feet (91 m) high, stretches through the center of the island and along its eastern coastline. The coasts of the island on the west and north form a low-lying tract that is fringed by the mangrove forests. Adinath Temple, a temple of Shiva, and a Buddhist pagoda are also located on this island.

Sonadia Island, a small crescent shaped island of only 9 square kilometres, it is 7-km north-west of Cox's Bazar. The western side of the island is sandy and different kinds of shells are found on the beach. Off the northern part of the island, there are beds of window pane oysters. During winter, fisherman set up temporary camps on the island and dries their catches of sea fish. Sonadia Island supports the last remaining part of mangrove forest in southeast Bangladesh. Sonadia's mangroves are distinct from the well-known sunderbans, due to their development in a coastal lagoon setting rather than in a delta.[20] Another attraction of this island is the sight of game birds migrating here in great numbers during the winter seasons.
