7Réunion Island, Indian Ocean
Réunion Island, a French overseas department in the Indian Ocean, has garnered a reputation for being one of the most shark-infested places in the world. Shark attacks have been a significant issue here, particularly involving bull sharks and tiger sharks. The island’s warm waters and rich fish populations attract these large predators, making certain areas—especially along the west coast—prone to shark activity. As a result, there are strict regulations for activities such as surfing and swimming in these areas. While the presence of sharks may deter some visitors, others are drawn to the island for its unique natural beauty and the opportunity to study these magnificent animals.
