We are traveling to Wuerzburg in early Dec to catch a river cruise tour. We have planned a full day to visit Wuerzburg - 1/2 day on our own, and 1/2 day with the tour company. We have an additional day in Wuerzburg which we have nothing planned . Any suggestions of near-by town(s) we should considering visiting for a day-trip? Or any additional activities/sightseeing we should consider doing in Wuerzburg?
your suggestions are most appreciated!
