Tom may recommend wine tours in Europe, but we're gonna have to say wine tours, shmine tours. Naked hiking in the Alps is where it's at:

Anyone is welcome to join for a part of a day, or for the entire walk, dressed or undressed, however their time, commitment or inclination allows. The preferred intention is to do all walks completely naked except for essential walking boots, sun hats and rucksacks. The exception to this is when going through towns and villages, when walking on tarmac, or when in a gasthof or restaurant. If anyone is uncertain as to dress code, or how to join in, please do not hesitate to send me an email for clarification.

The walks will be held in the first week in July (Sunday 1st July to Saturday 7th July 2007) at a location to be decided later, but somewhere near Salzburg. More information on naked hiking in Europe.
