Today Day 4 Portomarin to Ventas Naron, as you exit Portomarin crossing the river Miño, Galicia’s longest river, you then begin a steady uphill walk from 350m to 725m. This section on and off the road for 13 km is demanding so you should take it at a steady pace.
In Castromaior the circa 4BC to 1AD Roman ruins are well worth the short detour off the Camino.
When arriving in Ventas de Narón, visit the small 13th-century Ermita de Santa María Magdalena built by the Knights Templar. A beautiful testament to the rich history of Camino de Santiago.
