In addition to the usual fun and games, the Party of Swedes camp offers "several interesting lectures, speeches, workshops," the Swedish news agency TT reported.
Andreas Carlsson, one of the organizers, told the Dagens Nyheter newspaper the camp is not political. He said the secrecy comes from experience with harassment.
"We have a fixed gathering point but from there the directions are secret," he said.
Johannes Jakobsson is a writer for Expo, a magazine that investigates right-wing organizations. He told The Local the party undoubtedly hopes to indoctrinate young people.
"It is easier to reach young people with Nazi propaganda before they have really made their mind up on what Nazism stands for," he said.
The camp appears to be for all ages, with children getting in free to lure young families. But one group appears to be unwelcome -- those of non-European descent.
"You can have a foreign name, but if it is from outside Europe it becomes more difficult," Carlsson said. "And we don't necessarily see someone as Swedish just because they have Swedish citizenship."
