There's a small shop in most villages along the route, so resupply is easy. I also got most of my water from shops as there are sheep everywhere, so I didn't want to drink from streams.
Spent two nights on camp sites and one night wild camping.
The route was quite challenging: No markings, often the trail is very faint, a lot of fog above 400 m of elevation, one day full of rain and heavy wind and A LOT of mud! But very beautiful, I highly recommend it!
