Take a cross-border adventure on a day trip from Porto, Portugal to Galicia, Spain. This northern Spanish region is best known for being home to Santiago de Compostela, the famed finishing point for the Camino de Santiago pilgrimage path(s) where you’ll also find a magnificent UNESCO–listed cathedral, historic Old Town, and lively markets. Most tours typically include comfortable round-trip transportation (as well as help with border logistics), plus visits to the Portuguese border towns of Valença do Minho or coastal Viana do Castelo, for a holistic glimpse into Iberian culture and daily life.
