Wow! That would have been an awesome drive! Did you stop by any of the restaurants or vineyards? I saw some dotted by the lake, think the dining view would be so cool.
As to the station, not only that, I think a lot of the buildings in Porto have so much character, I still got a bunch of photos I haven't posted about yet
We were lucky enough to be shown around by a local. So he looks us to lots of cool places in Porto!
We just went to one where you could freecamp and do a tasting on a farm/vineyard and learnt a lot about the appellation. Really interesting.
The road was judged as one of best in world!
