10Praia de Boa Viagem, Brazil
Located in Recife, Brazil, Praia de Boa Viagem is famous for its golden sands and turquoise waters. However, it is also infamous for its shark attacks. This beach is considered one of the deadliest for shark encounters, particularly from bull sharks and tiger sharks, two species known for their aggressive behavior. The construction of a nearby port has disrupted the local ecosystem, driving sharks closer to shore. Despite warning signs, many visitors still swim in these waters, leading to unfortunate incidents. While the beach may look inviting, it’s essential to exercise caution here.
