Investors plan to set up a hotel catering exclusively to nudists in the picturesque Black Forest town of Freudenstadt, which incidentally translates as Town of Joys.

Guests will be required to remove their clothes at the entrance and must be naked at all times while on the premises, according to the strict house rules that have already been posted on the Internet.

"We hope to open as soon as possible," Silvia Probsthain, a member of staff at the planned Hotel Rosengarten, told SPIEGEL ONLINE. "It will be the first comprehensively nudist hotel in Germany." There are similar hotels catering for nudists in Scandinavia, Croatia and the south of France, said Probsthain.

The rules state that all guests must put towels on chairs and loungers before using them, that there be no sexual harassment and that all sexual activity in commonly accessible rooms is strictly forbidden. People who break the rules will have to put their clothes on and leave.

Freudenstadt's tourism director Michael Krause said the contracts for the hotel hadn't been finalized yet and that it was unclear when the project will go ahead. "I'm in two minds," Krause told SPIEGEL ONLINE. "It's always good if a new hotel is set up but I'd prefer a normal hotel concept."

Nude hiking is proving increasingly popular in Germany and two villages in the central Harz mountain range plan to mark special forest hiking routes for naked ramblers. The practice is frowned on in neighboring Switzerland, however, where authorities plan to fine such behavior.
