Changes

Going South can be hard, even when you start from within the nearby city of ''Gaia'', which is just across the Douro River. The best spot in Gaia is probably a roundabout, just after the last metro stop (and ironically, just past the main street that leads to the highwaymotorway). Keep walking straight along this main street, stay to the right as it drops down and becomes the highwaymotorway. You'll see a bridge connecting the two sides of the road that don't become highwaymotorway, and just past this: a roundabout, which also has a part leading to the highwaymotorway. This is an okay spot to stand, even at night, with plenty of room for cars and trucks to pull over.

You may hitch from the gas station close to metro station "Estadio do mar". At the roundabout, take Av. Calouste Gulbenkian, pass the School of design and you will see an entrance to costal highway coastal motorway A28 going North. People might also be going North using other highways motorways from there since there is a junction heading East close by.
