Off the beaten path with this question.

As we enter winter we were just asking ourselves how could we have long summer days year round without going to Australia 12 time zones away?

Are there any places in South America who have places like nudist campgrounds in the U.S.?

Looking for basically a safe, inexpensive campground to have a camper....... we know there is poverty and crime in Brazil and Argentina but does anything escape all that in the countryside?
