Ah, the French. This is from a campground somewhere in France (I should probably keep track of these things). They are way more relaxed about nudity than we are here in the prude USA. As a result nudism is much more common and nude beaches fairly ubiquitous.
This is a beautiful example of family nudism. Nudism is not sexual and can be enjoyed by all ages. In fact, kids are usually natural nudists as they haven't been indoctrinated their whole lives with "modesty" or "decency" rules. It's sad that once most people hit a certain age (usually puberty) they become ashamed of their bodies and lose the freedom of childhood innocence.
