We loved the cruise down the river to Durnstein through the Wachau valley and Durnstein itself was a beautiful little town. My husband hiked up to the castle ruins on the hill and said the view from the top was spectacular.
Avignon is the spectacular place to see. The tour to Pont-du-Gard is something to see. The time spent there was very peaceful. Uzes has spectacular architecture. The Pope's Palace is so unique with all the rooms and history.
