We have two nights to spend in the Wachau Valley area and towns this August before heading to Hallstatt, and wanted to get advice on what the best town to stay in is, and how to best do a full day tour of the towns/area? I've read about people doing day trips from Vienna to Melk, and then taking a boat down to Krems before heading back to Vienna. However since we have the time to stay in the area is there a day trip where you can take a boat to a few beautiful towns and then an easy bike back along the river?
We will have a full first day driving out of Vienna in the AM, and then a full second day in the Wachau valley. On the third day we will be driving to Hallstatt. Any "can't miss" things? All we know of so far is the Melk Abbey. Thanks so much!!
