We hiked up a mountain in the Rittersberg forest in Alsace, France to get to this castle called Chateau Ramstein. What a wonderful hike and you could hear the birds chirping so loud everywhere. I enjoyed that so much I even made a recording of it on my iPhone! We then hiked on further to yet another castle called Chateau Ortenbourg where we had a picnic. Both were in the Vosges mountains not too far from a town called Scherwiller. This one here was built by Albrecht Von Hagsburg after he came to thrown in 1298. It was his siege castle after he had burned down the one above. This one also was finally burned and destroyed by the Swedes in 1633.
Paris as metro stations. Amazing! And it's really simple too... you rent it, ride it and then return it to any station. It's a great way to get around!!
