I have not posted anything in the past two weeks because we took a trip to tour Bavaria, Germany, Lucerne, Switzerland and Innsbruck and Salzburg, Austria. I began to sort out some pictures I took once we got home. Here are the pictures of castles on the Rhine River when we started our tour from Mainz with four hours of river cruise toward Heidelberg. It was a beautiful section of the River for viewing many castles on the hill tops and on the river edge.

Gorgeous photos. I used to live in Germany; it’s a very photogenic country!
Impressive castles and some I even know. Most of the time castle are close to rivers. Nice shots Stephen.
