Mount of a Siradella Nature · O Grove, Salnés, Pontevedra Monte da Siradella, at 166 metres above sea level, is the highest point of the O Grove peninsula and its view takes in the A Lanzada beach and a good part of the municipality, together with the area's Complexo Intermareal. At its summit stands a nature interpretation centre that shows the ecological richness of this complex through information panels, photographs, bone remains of cetaceans and birds, shells and the model of a batea (mussel raft). From the Siradella viewpoint a platform on the rock is reached, among numerous weathered crags, the best known of which is called Pedra Cabaleira. Nearby lie the still-unexcavated remains of an old fortified castro. Photo: Triplecaña (CC BY-SA 4.0) What to see and do in O Grove
