After Amsterdam our tour headed south into Germany, first stop - Cologne. We didn't have long there but the cathedral was quite impressive and daunting at 157m tall.
Beer for lunch :)
Cologne Railway Station
A cruise along the Rhine River. Some of the vineyards in Rhineland are on ridiculous slopes. Some even needing a cable chairlift to get the pickers down the slope for harvesting.
As usual, more to be found here.
