In O Pobo / Santa Marta an alternative route into Pontevedra presents itself on the left side of the road.
Turn Left to follow signs towards the Rio Tomeza. This path is 3.6 km to the Pontevedra Albergue (at the start of town near the train/bus stations), and the original road route to the same point is 2.8km.
The following towns are set apart in this guide as a detour only because there are no points along the alternative river route that can be used to distinguish it from the road. Both are suitable.
