The path to Maia takes you over the N13 and up the hillside past the zoo. Stay on this road as it merges with a few others, always heading uphill until you arrive at the church, which is the highest point in town.
Exit via the one-way road behind the church and to the left, back downhill. Follow the arrows to the tunnel under the highway. Into Godim and further to Guarda, and beyond that the Zona Industrial of Maia.
