I walked via Pola in April 2011. When I got to the turn off, the track was covered in fog. The following day, I stopped in Berducedo and spoke to the ones who had gone via Borres. They did say it was basic and that you needed to carry your own food.
Then in August 2011, I rode my bike on the Primitivo and when I got to the turn off for Hospitales, I took the track and went up. I was amazed at how well this track is marked, personally, I would no thave got lost in the fog in April.
When I was on the VDLP this year, I spoke to a Spaniard and he said that he had walked this way in late December. There was snow on the track and he never lost a marker.
When do you plan to go as I will be on the Primitivo again in July?
