I have just read(having been too busy during tha last part of last week)
your posting.Welcome to this list.
You are going to enjoy Portugal,a country that I love so much.I hear that
Colette is back from her recent tour there,so I'll let her be your up-to-date
guide to the parts of the country she travelled through.I'll be glad,in
turn,to be of help on any other area of the country(continental Portugal
only,excluding Tras-Ús-Montes,the only region I don't know),although I
never used railway as a mean of transportation.
Please ask again,but try to be more specific:how long will you be touring
Portugal;in which season;are you thinking of heading north or south from
Lisbon;are you interested in any peculiar issue,and so on...
I think one of the best railway itineraries is from Porto along the Douro
river;train is reputed to be the best way you can enjoy the splendid countryside
where Port wine is produced.
That's all for now,ciao from Italy.P.S.Where are you from?
