Although there are many places on the islands for admiring its landscape, only some of them are considered special due to their high scenic interest and location, and hence recommended for most visitors. In Ons, the Fedorentos viewpoint is the best known as it offers an impressive panorama toward the south onto the island of Onza, the Cíes Islands, and the nearest continental zone.
Although it is not signposted as a viewpoint, the Ons Lighthouse surroundings offer spectacular views on to the Rías of Pontevedra and Arousa (with the island of Salvora at its mouth).
