The so-called Rías Baixas come together between Baiona and Fisterra. These are the largest estuaries and those that spread uniformly from south-west to north-east, and are the Vigo, Pontevedra, Arousa and Muros-Noia. On its rough littoral, the coastal area of cliffs, rocks and sharp falls combine with broad areas of sand accessible from land, following the road network, or from the sea from one of the numerous ports.
From the viewpoint of the climate, temperatures are mild a large part of the year and there is considerable rainfall in autumn and winter, which causes the development of large forest masses blooming greenness and that travellers see at first sight.
