At Gião - Joudina the camino has followed alongside the narrow N306 for about 2km.
The road narrows ahead, and the going was sufficiently dangerous for the camino to be rerouted to the east along a much quieter road. The distance added is 1km, but the route is pretty enough and peaceful enough to feel shorter than along the road.
There are also plenty of bars along the way, and the albergue of Vairão is best reached via the detour as well.
Turn right and head towards Igreja.
