This is a realy nice mountain road with a lot of corners (some fast some a litle more tight). The asphalt is realy good, and the views are quite nice. It conects "Sever do Vouga" to "Vale de Cambra", and passes through 1 ou 2 villages so just pay atention in those areas for some traffic, but otherwise is you, the road and the mountain. I leave you with the fotos of the road, the views and the bike, taken by my friend @luisborie.
