Where are the trails adequate for barefoot walking (novices) near the Nuremberg (Franconian Switzerland, Franconian Alps)? I've noticed that most of trails in this region are partially or wholly graveled, which is very hard for barefoot novice (not to say, practically inaccessible).

I can walk a few km barefoot on ground path, but on graveled one I must give up after a few dozen meters.

Or, maybe, there are some trails specially designed for barefoot walkers?
