Castelo de Monterreal
Perched on a rocky headland jutting into the Ría de Vigo, the Castelo de Monterreal is one of the best-preserved medieval fortresses on the Galician coast. Walking its complete circuit of battlements with the open Atlantic on three sides feels genuinely cinematic.
A fortress with real history
Built in the 10th century and expanded by the Catholic Monarchs in the 15th, Monterreal was the place where Christopher Columbus sheltered after his second voyage to the Americas in 1496 — a fact commemorated by a statue inside the walls.
The castle encircles the entire old town of Baiona, so wandering inside means ducking into Romanesque chapels, posing on cannon platforms and discovering quiet garden corners all within the same loop.
Walking the walls
The 3 km perimeter walk along the battlements is free to stroll and takes roughly 45 minutes at a leisurely pace. Every bend delivers a different panorama: the Cíes Islands to the north, the open Atlantic to the west and the green Galician hills to the east.
Sunset from the western tower turns the granite walls amber and the sea molten gold — arrive at least 30 minutes before dusk to claim a good spot on the ramparts.
