One of the very first things hubby and I did when we got to Germany was go on a Rhine River cruise. Crystal and her husband had done it before and said that it was a lot of fun. This was taken from the Rheinstein Castle. It was very early in the morning.
One of the other cruises going by a small village.
This is a shot of the tunnel entrance on the side of the river. Look at the small tower to the side.
A castle on the hillside. I took so many pictures of castles. Hubby was fascinated!
There are a few more, but I'll leave them for another time!
