Overview

The Porto-do-Son branch is the link that connects the The Muros-Noia Estuary Trail makes it a complete Way of St. James: Only when you walk both branches together do you reach the 100 kilometers required for the Compostela. The branch begins at the port of Porto do Son – a small fishing village on the south side of the Ría de Muros y Noia – and follows the coastline directly for long stretches all the way to Noia. At just 16.3 km, it can be completed in a leisurely half-day.

What makes it worth seeing anyway: three hours along one of Galicia’s most beautiful stretches of coastline. Sandy beaches, the sparkling Atlantic to your right, rolling hills to your left—and directly across on the northern shore, the striking Monte Louro as a constant companion. Anyone who also wants to take a detour to the Barona Castle If you include a visit here (4 km from Porto do Son), you’ll experience one of Galicia’s most impressive Iron Age castros—located on a peninsula jutting out into the sea.

Other Names

In pilgrim forums and on route maps, this leg appears under various names: “Porto-do-Son-Ast,” “Ast Porto do Son,” or “Etapa 1P” (P for Portosín, near Gronze). Officially, it is the southern coastal route of the The Muros-Noia Estuary Trail. There is no specific tradition or historical name associated with it—the trail was intentionally created as a supplementary branch when the main trail was officially recognized in 2020.

Who is this route ideal for—and who might it not be ideal for?

This branch is Requirement For anyone aiming to earn the Compostela for the Camino de la Ría de Muros-Noia: Without Porto do Son, the Muros branch alone isn’t enough to reach the 100 km. It’s also perfect for pilgrims who love coastal scenery: beaches, the sea, a harbor atmosphere, and a Celtic-Galician fort as a bonus. Its low difficulty level also makes it ideal for those taking shorter hikes or as a “starting stage.”

This branch is less suitable if you’re looking for an intense historical pilgrimage route or dense natural terrain: The Porto-do-Son branch has a higher proportion of paved surfaces than the main Muros branch, and its history is pragmatic—not historical. Even those who prefer a pilgrimage experience without beach visits may find more distractions than spiritual fulfillment here.

Route & Landscape

The First Section Porto do Son – Portosín (8 km) The trail starts right at the fishing harbor and follows the coast south. Passing the Church of San Vicente de Noal, the trail leads through Noal and Loreto—with the Chapel of Nuestra Señora de Loreto offering a welcome spot to rest. A brief detour inland through the villages of Orseño and Quintáns, then back to the water. The Langáño Beach – a long sandy beach with a direct view of Monte Louro – almost inevitably invites you to take a quick dip. The halfway point is Portosín, with its marina, the largest in the Ría.

The Second Section Portosín – Noia (7.7 km) The coastal scenery continues: the beaches of Gafa and A Hornanda, the Ermita de Pardiñas, and well-preserved Galician hamlets. Passing through Taramancos and the charming village of O Obre—with its medieval little bridge, A Chaínza—you enter Noia through the Gate of the Pilgrim (also known as Porta do Tapal), the city’s historic pilgrimage gate. A fitting end to a relaxing day-long coastal tour.

Baróña Castle

Anyone who starts the trail from Porto do Son won't be able to miss the Baróña Castle gone—at least not without savoring it. Just 4 km from Porto do Son, on a peninsula jutting out into the sea, stands a Celtic-Galician fortified village dating from the 4th century B.C.: four terraces, 20 round stone houses, and the Atlantic Ocean on three sides. It is one of the best-preserved and most spectacular castros in Galicia.

The Castro isn't directly on the official trail, but a detour (about 8 km round trip on foot) is well worth it. Alternatively: Arrive in Porto do Son the day before and explore the Castro as an afternoon excursion—that way, you’ll start the next morning feeling refreshed and with the satisfaction of having already seen one of Galicia’s most beautiful Celtic relics.

Highlights Along the Way

• Baróña Castle – A Celto-Galician fortified village on a coastal peninsula (a 4-km detour from Porto do Son); 4th century B.C., one of the most spectacular castros in Galicia.
• Langáño Beach – A long sandy beach halfway along the route; with a view of Monte Louro; perfect for a quick swim.
• Portosín – The largest marina on the Ría; good dining options halfway along the route.
• Gafa & A Hornanda Beaches – Wild stretches of coastline in the second part; hardly any tourists.
• Gate of the Pilgrim – Historic Pilgrimage Gate; the classic entrance to Noia’s medieval old town.
• Monte Louro – Not on this branch, but always visible across the way; the Ría’s landmark accompanies you the whole way.
