On the right bank of the river of the same name, we come upon Orio, a residential seaside town where you can see the Church of San Nicolás and the Shrine of San Martín, both of which are well worth a visit. The color yellow is everywhere in this town. This is the color of Orio’s trainera (a type of boat), which is the most famous one on the Cantabrian Sea. One of Orio’s main attractions is the beach and the town’s proximity to Pagoeta Natural Park. If you plan on sleeping in Orio, we’ll tell you about the best places to stay.
