Food for thougt for some road trips.

Most scenic stretch along the Rhine River: The 41 miles between the German towns of Koblenz and Rudesheim.

Don’t miss: This entire stretch was designated a UNESCO World Heritage Site in 2002 in honor of both its dramatic natural beauty and historic significance. The banks are lined with—you guessed it—castle after castle, about one per mile. Marksburg is among the best preserved (the squeamish might want to skip the torture chamber). Rudesheim, one of the most popular winemaking towns in the Rhine Valley, is perpetually packed with tourists. You’re better off hopping on an open-roofed gondola or a chairlift over the Niederwald recreational area for an unbeatable aerial view of sloping vineyards and the river valley.
