Probably one of the most useful sites out there on Portugal. From the Portugal Tourist Board – lots and lots of useful information about visiting the Douro Valley. Make sure you follow them on Twitter too – always something good being tweeted daily.
The Douro Valley could as easily be called the enchanted valley, such is the beauty and magic that its landscapes offer.
Departing from Porto, where the river flows into the sea and where the Douro wines (table wines and Port wine), produced on its hillsides, also end up, there are various ways to get to know this cultural landscape, listed as a World Heritage Site: by road, by train, on a cruise boat and even by helicopter. None will leave you indifferent.
