5Boa Viagem Beach – Brazil

Brazil has more than 4,500 miles of coastline and some of the world’s most inviting and photographed beaches. But if you’re visiting Recife, a former favorite among surfers, there is one beach that is best left alone.

Boa Viagem Beach has one of the highest shark attack rates in the world – 56 in the last 20 years, with a death rate of about 37 percent. Sharks use the trench off the coast as a migratory route and do their hunting in the surrounding shallows.
