This river cruise is different from most of the others in Europe in that it focuses on the Port wine trade and the vineyards that supply it. The cruise goes through locks at 5 hydroelectric dams completed only in 1985.
Highlights:
* Cruising the upper Douro with the views of the steep sided vineyards
Well appointed cabin given the restrictions of a river boat.
The day trip to Salamanca was excellent, could have spent longer there
Not much to the port except an interesting railway station and proximity to the vineyards
