Rambling vineyards and charming native farms cling to the steep sides of the Douro River Valley, creating an incomparable backdrop to one of Europe’s most unspoiled regions and to Port country— the world’s oldest demarcated wine region. Sail roundtrip from Porto, the beautiful “City of Bridges”; visit Regua, the ‘capital’ of the Douro Valley; and marvel at Salamanca, the UNESCO-designated “Golden City.” Taste wines from historic wineries and soak up the genuine beauty of one of Europe’s most unadulterated landscapes.
