Before the ship sets sail again during lunch and heads east, you will enjoy a morning bike tour north of the river valley. In the mountainous hinterland of the river, you cross the ark to the tiny hamlet of Sabrosa, the birthplace of Magellan. Then, through vineyards, you return to the ship along the river loops of the Rio Pinhão, which flows into the Douro River.
When the weather is nice in the afternoon, you can enjoy the river landscape on the sundeck as the ship approaches the Spanish border. The Douro is the most water-rich river in the Iberian Peninsula and navigable up to 14 km into Spain, where a 60m high hydroelectric power station prevents the continuation of the journey from Vega de Terron. Barca d'Alva is the last place before the Spanish border.
From here, the Douro separates the two Iberian nations in the middle of the river. The railway line that connected the remote Douro valley to the rest of the world ended in Barca in 1985. Since then, the place has become a sleeping beauty, and you almost feel at the end of the world—a wonderfully remote location in the Douro Natural Park.
