Staithes Beach, UK
You won’t find any dangerous sea creatures waiting to take off your leg at Staithes Beach. That being said, you might still lose a limb from a gnarly bacterial infection! Sure, it looks photographic, but the bacteria and viruses are naked to the human eye. With something like this, you’d think it would be taken care of, but nope!
Thanks to the sewage that runs into the ocean here, it’s known as one of the most polluted beaches in Europe. The microscopic nasties lurking in the water here include meningitis and E. coli! Every year, the European Union does a test to make sure beaches are safe, and this one consistently fails to reach the minimum standards.
