This cruise was chosen as friends recommended it as a scenic Viking River Tour of the River Douro midst wine country. We also chose it at the particular time we travelled as Portugal had, along with Cuba, the highest vaccination rate in the world (98%). We'd not visited Portugal before and thoroughly enjoyed our 14 days there. There is already talk of a return to this charming and diverse country. The river cruise on the Douro was the top highlight although there were many. This was our 2nd Viking river cruise. The other was the Rhine River from Amsterdam to Basil. That cruise was very good although the Rhine is a much more commercial river hence a lot less quiet. We preferred the Douro. A day trip by coach to Salmanca Spain was very enjoyable. Despite that I don't enjoy "bus" travel the coach travel is very comfortable and if you want to see as much of Portugal and dip into Spain coach travel is unavoidable. The tour guide was excellent on every trip we took off ship by coach which I believe was approximately 4 times during the river tour.
