The highest point of the peninsula O Grove is located in Mt. A Siradella. For this reason, it is not surprising that several viewpoints are located both on its summit and on its slopes. The best known is, without a doubt, the one with the same name. Thus, next to the Aula da Natureza and at the foot of a huge cavalry stone stands the viewpoint of A Siradella, from where you can get spectacular views of the isthmus that connects O Grove to the rest of the continent, the beach of A Lanzada and the archipelago of the Ons islands, belonging to the Atlantic Islands National Park.
