All services in Carreço are located along the main road. To get there you will need to turn left to cross the railway, and follow the road downhill to the roundabout. Turn left at the roundabout, heading south (with the water on your right).
If you choose to keep on the camino through Carreço, turn away from the bridge and keep to the east of the tracks. It won't be long before the camino turns back to the tracks and crosses at a level crossing. It will arrive at the church and pass behind it. Arrows are scarce to non-existent here, just keep to this same road a short distance until it merges with a larger road and turn right towards the train station.
Where this road ends turn right and back over the railway in the direction of "Paço - Carreço". A short distance on the camino turns left at the second street, there is an arrow and a marker for the PR8 hiking trail. Arrows will guide you through town, past the albergue, and at the last junction at the last house in town, keep left and into the forest. The way is anything but straight but is well indicated.
You will emerge from the forest at the edge of the town of Afife, and subsequently skirts around the town thereby avoiding all of the services available there. The way is marked and winding along cobbled roads. It will make its way over a small river and continue to climb up through the forest to a road and the stone cross cruzeiro.
