This is the early morning mist on the River Douro in northern Portugal. The Douro valley has its own micro climate enabling it to grow grapes like nowhere else in the world. Couple this with 17th century British ingenuity and you create Port, that wonderful wine that has graced so many dinner tables.
The picture was taken from the sundeck of the Douro Spirit on a river cruise organised by Uniworld River Cruises who I can heartily recommend. You can see the navigation bouys in the river, at times were in steep barren rock faced gorges with Golden Eagles flying alongside and other times the high open valley with sides covered with vineyards. Try the white port it's amazing!
