Crossing the Spanish - Portugese border, the Deuro changes its name to Douro, but continues to be as spectacular in Portuguese territory. The Douro International Natural Park begins here. Do not miss the rock art of the Côa Valley, which is one of the most extensive outdoor locations with samples of Paleolithic art, and make river cruises with stops at wineries to taste the wines of the famous wine region of Alto Duero. On the countryside of Portugal, an hour from Porto, where the Douro flows into the Atlantic Ocean, you can enjoy the passage of the river through naturalreserves and interesting towns, such as Pinhao, Peso da Régua or Santa Cruz do Douro. Although, undoubtedly, the main activities revolve around wine and wines from the Douro Valley (Unesco World Heritage Site). Visit one of the Rusticae boutique hotels!
