This is a short side branch, not a big adventure. It’s one day’s walk along the southern side of the ría, from Porto do Son to Noia. You don’t need to train for it. It’s handy if you want to join the Camino de la Ría de Muros-Noia from another direction, or if you simply fancy a lovely day beside the water.
You set off on the coast, with salt in the air. The highest point stays low, around sixty metres, and the climbs are short. That makes just over 18 kilometres of walking, which you can comfortably do in a day. Little by little you work your way into the ría and Noia comes closer. There you join the route from Muros. If you want to carry on to Santiago, you simply keep walking from there.
The best time to go is May to September. It’s dry enough then to walk this stretch at your own pace. In the winter months it’s cool and wet, with as many as sixteen rainy days a month. That makes for a different kind of day.
Want to earn the Compostela? This side branch on its own is too short. Start earlier, for example in Finisterre or Muxía.
