Wertheim is a small walk able city of old cobblestone streets; a step back in time. We sailed all morning admiring the river scenery and then had a glassblower jump abroad at one of the canals. He treated us to a glass blowing demonstration and invited us to see his wares when we arrived later in the day in the town. But before strolling the town we hiked up to the ruins of Burg Wertheim (castle) and the major landmark of the area. Wertheim has a medieval town center with half-timbered houses, small streets and lots of little outdoor cafes. A great place to drink a cold beer after hiking up to the Burg.
