Here are the beaches that you might want to cross out of your list for your next vacation.

Infested with sharks

Recife Beach in Brazil is a favorite hangout place of predatory sharks. The waters are reported to have 46 shark attacks with 14 of these resulting to human deaths.

Sunbathing with cows

Cows are so respected in India that they are allowed to roam everywhere, even at the beach. Goa Beach is full of these sacred cows. Unless you want a cow to lather sunblock on your back while you smell the pervasive odor of cow manure, avoid this beach.

Syringes and broken glass

The beaches in Port Philip Bay, Australia are not for tourists who want scratch-free sunbathing. The sandy areas are filled with booby traps of broken glass and syringes. The storm-water overflow and litterbugs are to be blamed.

Overcrowded

Fujiazhuang Beach or Xinghai Beach in China brings beach lovers close to one another. Too close actually that beachgoers don't have privacy in their beach vacation. It is a favorite place of Japanese, Koreans, and Russians. Now if you want a little bit of space, avoid this beach.

Near trashy bars

Thanks to its location near over 130 bars offering cheap drinks, Blackpool in England is home to trashiest tourists. Beaching here with a family is strictly discouraged as everywhere, even during the day, the beach is proliferated by drunk tourists, vomit, and broken bottles. To spell it out, this beach is not family-friendly.

Most polluted beach

California is supposed to be the go-to place when it comes to fun, entertainment and beaches. Doheny State Beach offers the opposite. It is famous for being ranked as the most polluted beach in the state, having gained that label for three consecutive years in the early 2000s. It has a record 91 percent level of bacterial infestation.

Lava rocks everywhere

The beaches around Kona, Hawaii are not the safest beaches that a vacationer would visit. Sharp lava rocks surround Hon'l Beach. To add insult to the injury, there are plenty of signs posted to warn against swimming thanks to unpredictable water conditions.
