Viewpoint and coastal walk · Half a day · 166 m above the isthmus and Ons · Wooden walkway beside the sea · Free

Two stops in the western half of the peninsula, a few minutes by car from each other: above, the highest point of O Grove, with A Lanzada beach and the Ons islands at your feet; below, at San Vicente do Mar, a wooden walkway that skirts the coast among rocks, coves and small beaches. Together they fill a morning or an afternoon without paying anything and without booking.
The A Siradella viewpoint
Monte A Siradella rises 166 metres above the sea. At the top there are two viewpoints: the first, next to the Aula da Natureza and at the foot of an enormous piedra caballera (rocking stone), a large rock balanced on another, is easy to reach; the second, next to a geodetic marker a few metres higher, is reached by a path. From there you see the isthmus and the tongue of sand that separates the Ría de Arousa from the Atlantic, the whole of A Lanzada beach, the Ons archipelago and, on clear days, the Cíes.
You drive up and walk only the last 250 metres. There is a large car park and a picnic area with stone tables and benches, so it is a good place for a sandwich lunch.
The Pedras Negras walk
At San Vicente do Mar, the walk starts at the Pedras Negras marina and continues on wooden walkways right beside the sea, adapted to the rocks and marked with large stones shaped by erosion. It skirts the beaches of Burato da Londra, Farruco and A Barrosa, passes between rocks at the cove of Fervide and ends at the viewpoint of Canelas beach, just before an old military battery. There are benches along the way to sit with the Ons islands in front of you.
If you have energy left, continue along the coast around the battery: the path links with the PR-G 116 Con Negro, one of the parish's two waymarked routes. Near San Vicente are also the archaeological site of Adro Vello, a Bien de Interés Cultural, and the Quinteiro de Temperán, an interpretation centre for rural culture.
How to organise it
Go up first to A Siradella in the morning light or at the end of the afternoon, when the sun sinks over Ons, and then go down to San Vicente. Leave the car at the Pedras Negras port and do the walk to Canelas and back the same way. With a dog, keep it on a lead on the walkway; on the beaches, ask the rules first at the tourist office. For lunch nearby, Culler de Pau is in Reboredo, a few minutes by car; book beforehand.
