October 2020 - This was the most disappointing Whs on our trip, certainly by own fault. We have not arranged anything, since we spent the 2 days before arriving here in the Serra de Estrella, without recharging mobiles. We arrived at the museum, which is where most tourist stop only and visited the exposition. No guided tours were available for that day, next day only afternoon. We had seen Rock carvings before e.g Valcamonica, and they do not belong to my favorites anyway. We drove down to the Coa and could have a closer look on the most northern core Zone. For my standards that’s is enough of an visit to check this site. Please don‘t blame me. I will leave no rating since I cannot evaluate the essence of the OUV. Our schedule was tight, so we continued to Pinhao still that day.
