The feeback of  a bergfex.com User to the ‘Spiagge della Mughera’ trail near Limone, which you’ve rated T6 on the map.

We followed the path up to an altitude of about 600 m. It was already clear from the exit of the tunnel that this trail effectively no longer exists. After we had passed the first rockfall barrier on the right and the second on the left – both sections were heavily overgrown – we could still make out a few scattered traces of old red-and-white markings.

At the third rockfall barrier, however, all traces of the path came to a complete end: there were neither markings nor recognisable footpaths nor any other signs of a route. The waypoints marked on the map eventually led us into very steep, grassy terrain with loose rock, which, in our view, poses a significant safety risk.
In my opinion, the current marking of this old path no longer makes sense. I would therefore recommend removing it from the interactive map or at least clearly marking it as no longer passable.
