Praia do Pinho

Location: Brazil
What's Cool: Less-developed and more pristine than nearby beaches
-----------------------------------------
Although the barely-there, dental-floss bikini debuted here, nude beaches in Brazil are somewhat rare. However, naturism has caught on in some parts of the country, including Praia do Pinho (a.k.a. Pinho Beach), located in the southern state of Santa Catarina. Pinho opened in 1987 as the first sanctioned au naturel beach, and nudists who frequent this area make a point of saying "clothing is not an option" despite the strand's official description as clothing-optional. Balneário Camboriú, the chic city home to Pinho Beach, is very popular with beachgoers from Argentina, Uruguay and elsewhere, and its population is said to increase ten-fold from December through February. Travelers wishing to avoid the crowds should visit during November or March, when the weather is just as balmy.
