Fraser Island, Australia
Famous for its eco-tourism, Fraser Island attracts adventure-seekers from all over the world. But the beach conditions are unpredictable, and attacks by the island’s dingo population have resulted in deaths. Visitors are instructed to avoid running down sand dunes and diving into lakes. Area officials also suggest folks avoid swimming on the eastern side of the island as conditions are extremely hazardous.
Amazon Beaches, South America
You’ll find plenty of animals that pose an issue for swimmers here, such as anacondas, electric eels, piranhas, and vampire fish (candiru). Unfortunately, the area is also home to quite a bit of gang-related crime, like drug trafficking and robberies. Hundreds of small rivers make it easier for criminals to make their escape, like modern-day pirates.
Northern Territory, Australia
Australia’s poisonous wildlife isn’t limited to land species. In this far-flung corner of the continent, you’ll share the water with ravenous saltwater crocs, stonefish, jellyfish, and so much more. And the area is so isolated (most beaches don’t have names; the area is known as Arnhem Land) that any call for help may go unanswered for a long time.
