7Boa Viagem Beach, Brazil
Boa Viagem Beach in Recife attracts thousands with its warm waters and urban convenience, but it’s also known for having one of the world’s highest numbers of shark attacks.
Since the 1990s, the region has seen a series of aggressive incidents—many fatal—mostly involving tiger sharks and bull sharks. Sediment disruption from port construction altered marine migration routes, bringing sharks closer to swimmers. Despite warning signs lining the coast, many visitors still take the risk.
