Top Reasons to Go to The Bodensee

Altes Schloss in Meersburg: Explore the oldest continuously inhabited castle in Germany, from the sinister dungeons to the imposing knights' hall with its panoramic view over the lake.

Schloss Salem, near Überlingen: The castle itself has plenty to see, what with furnished rooms, stables, gardens, and museums all on the site; an added bonus is the 8-km (5-mi) walking path that leads cross-country from its grounds to Wallfahrtskirche Birnau.

Wallfahrtskirche Birnau, near Überlingen: A vineyard slopes down from this pilgrimage church to a castle on the lakeshore. The scene inside belies the church's plain exterior: it is a riot of color and embellishment. The Honigschlecker ("honey sucker"), a gold-and-white cherub beside the altar, is dedicated to St. Bernard of Clairvaux,"whose words are sweet as honey."

Mainau Island: More than one million tulips and narcissi grace the flower island of Mainau in spring, and they are later followed by rhododendrons and azaleas, roses, and dahlias. A boat trip is the most delightful way to get there, and you'll have the best views of Mainau castle on its small hill.

Zeppelin Museum, Friedrichshafen: Step inside the gracious passenger rooms of the airship, and you may find yourself questioning whether the air transport of today, though undeniably bigger and faster, is a real improvement.
