Someone has told me that in Brazil you can see lots of beaches where most of the traveler bathing nude in sea. Is that true? If yes, then please advice me few Brazil beaches where i can go with my mother and father.

That´s not true! People go to the beach and have fun with family! Nobody nude... there are beaches to that and it´s far of the "tour area" !!!

Don´t worry, go to teh beach and have fun but don´t forget you sunblock!
