If you are accustomed to using road signs to know where you are, then Peñaflor might confuse you. It is signed twice, once before the bridge and again afterward. For the sake of distance measurements, this guide uses the latter as it is closer to the actual town.
However! If you are looking for the bar, it is the one that is before the bridge.
The camino leaves the main roads and crosses underneath the railway in Peñaflor, and will cross back over them at the outskirts of Grado.
