The mirador is situated on a natural balcony that predates the modern road infrastructure, traditionally used by locals to track fishing vessel activity.
The viewpoint is aligned to provide a direct sightline toward the island of Ons, which is part of the Atlantic Islands of Galicia National Park.
It is frequently used by ornithologists to observe migratory birds moving along the Ría de Pontevedra corridor.
The stone construction uses local granite, reflecting the primary geological resource of the Galician Massif.
Mirador A Granxa is an elevated observation point located in the Rias Baixas region, overlooking the Atlantic coastline of Sanxenxo. The vantage point provides panoramic views of the Pontevedra estuary, specifically framing the Ría de Pontevedra and the surrounding coastal topography. It is positioned directly along the PO-308 road, serving as a prominent stop for travelers navigating the coastline between Sanxenxo and O Grove. The site features stone masonry elements consistent with traditional Galician public landscaping. The elevated platform allows for clear visibility of the nearby Ons Island archipelago on horizon days. As a public mirador, it functions as a strategic rest stop for motorists and hikers exploring the coastal route.

Visit during low tide to observe the changing coastal geography and exposed sandbars in the estuary.
Do not attempt to pull off the road at peak traffic hours, as parking space is extremely limited and maneuvers can be hazardous.
