From Outeiro the camino passes through Lestedo (3.7 km), A Susana (bar, pharmacy) (3.4 km), Aldrei (3.1 km), and Santa Lucía (bar) (2.3 km).
The camino enters Santiago from the neighborhood of Sar, named for the modest river that flows through it. Here you'll find the Colegiata de Santa María a Real de Sar, a 12th-century church worth a short visit -- it's to your left just after crossing the river. From the church, the camino follows the same road and eventually climbs steeply uphill to the old town. At the top, the arrows can be hard to find. Cross the road and enter the old town through the last standing gate, the Porta de Mazarelos. Continue straight through (against traffic). You'll pass a statue of Alfonso II at the highest point of Santiago, and from here keep going straight where the road narrows. At the next crossroads, turn left steeply downhill. At the bottom stands the Cathedral.
