Probably the world's first, a nudist-only hotel is all set to open in Germany's Black Forest region. Yes, you have heard it right.

All the hotel guests will be required to leave their clothes at reception while checking-in and must be naked at all times when on the premises -- "or they will be required to leave", The Daily Telegraph reported.

"We hope to open as soon as possible. It will be the first comprehensively nudist hotel in Germany," a member of staff at the planned Hotel Rosengarten, Silvia Probsthain was quoted by the British newspaper as saying.

The hotel 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.

The hotel is being built in Freudenstadt, which translates into 'Town of Joys. Freudenstadt's Tourism director Michael Krause said: "I'm in two minds. 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 neighbouring Switzerland, however, where authorities plan to fine such behaviour.
