Yesterday we caught a train south from Frankfurt for about 3 hrs to Donaueschingen, which is the source of the Donau (Danube) and biked our first fantastic 40km along the river valley and small villages. We stayed the night in Tuttlingen. We have had some light showers but nothing major. We have already met lots of nice and helpful people along our way.
Photo's below are of our bike and trailer on the train to Donaueschingen, and then Sandy at the source (spring) of the Donau.
