They’re getting bum-rushed.

A famed nudist vacation hotspot in the South of France has become overrun with globe-trotting swingers who aren’t shy about getting frisky in the sand, according to longtime visitors.

Cap d’Agde — one of the world’s largest naturist-style retreats — is now overpopulated with sex-driven tourists who are apparently notorious for engaging in sex acts on the beach.

“It’s made the place far more exclusive, creating a clear separation between the original naturist crowd and the new generation of lifestyle visitors,” Barbara, a Brit who used to come to the spot every year with her husband, told the Sun.

“Since we first started coming to the village around 30 years ago, the clientele has changed massively.”

While the area — dubbed the “naked city” — has long been filled with visitors roaming the town and frequenting restaurants in the nude, open sex sessions are now unfolding in the middle of the beach, according to the peeved nudists.

Despite signs warning against “sexual exhibitionism” and hefty fines, locals say it does little to deter the seedy swingers.

Now, Barbara said, she’ll only visit in the summer — and even then, she refuses to set foot on the beach.

“Both security and lifeguards and police are in the tower during the summer months, all day long,” she said.

During the peak months, Cap d’Agde — located roughly an hour from Montpellier — attracts some 40,000 visitors per day.
