It seems that we have no good value to mark surface of path of rocky paths.

surface=gravel fits for surface of small rocks (almost always man made, though
especially in mountains some may be of a natural origin)

surface=fine_gravel fits for small gravel

surface=unhewn_cobblestone =sett =paving_stones for processed rocks

surface=ground is not specific at all (though sometimes useful to avoid 
splitting
way into 191919 parts)

suface=earth / dirt for exposed soil
surface=mudĀ  for exposed soil that is typically full of water

But it seems that we have no tag for exposed rock that ends as surface of path.
It is typical on mountainous trails. See for example:

surface=rock
surface=bare_rock (????)

there is also case of surface made of unprocessed rocks (typically on trails
with heavy use to protect area from erosion and tourists from mud)

surface=rock? other tag?

(some time ago I floated idea of using surface=unhewn_cobblestone for them,
but it was not liked by anyone -
