Overview: Dubbed the Venice of Bavaria, because of its location at the confluence of the Danube, Inn and Ilz rivers, this compact medieval city with two castles and a mountaintop monastery, packs a delightful punch. Napoleon declared it Germany's most beautiful burg. You'll be a fan, too.
Don't miss: A stroll along Old Town's narrow, cobbled lanes chockablock with confection-colored buildings from the 15th to 18th centuries. Shops selling Bavarian dirndls and lederhosen abut art galleries showcasing edgier fare. Take in an organ concert at the over-the-top ornate St. Stephen's Cathedral Monday–Saturday from May to October. The cathedral pulls out all the stops in its Baroque flourishes, and so do the musicians at the keyboard of Europe's largest pipe organ. It's a feast for the eyes and the ears.
Independent Meanderings: Enjoy the views -- and work off the strudel -- with a panoramic tour starting from the hilltop Mariahilf Monastery on the city's south side, through Old Town and along the Inn River, and then across the Danube and into the northside hills, site of Veste Oberhaus. The grand fortress complex dates to the 13th century.
Hidden gem: The 321-step pilgrimage staircase at the Mariahilf Monastery sports - covered passageway adorned with hundreds of folk-art depictions made by true believers.
Active Pursuits: Hike the Passau hills or book a bike and ride the flat riverfront path.

Insider tip: Sample local gingerbread at Cafe Simon (Rindermarkt 10) on its flower-filled patio. In business since 1903, it makes the treat the old-fashioned way, with honey. Another sweet spot: Cafe Greindl (Witgasse 8) is a cheerful tearoom serving to-die-for cakes, strudels and more. (Get half off on some pastries after 5 p.m.) Dachshund-lovers will want to make a beeline for the Dachshund Museum
