The upper Mississippi River

For third-place honors, we turn to an area less celebrated than others, but nonetheless packed with the unique beauty our nation abounds in. Its low profile makes it all the more charming. To truly appreciate the Mississippi, we leave the familiar territory of Huck and Tom and take a spin on the Great River Road as it runs alongside Old Muddy's upper reaches through Illinois, Iowa, Wisconsin and Minnesota.

One of the nation's most scenic routes, it winds over hills, atop towering bluffs and through one 19th-century river town after another. The sites along the way read like chapters in American history. Ancient Indian burial mounds punctuate rolling parkland, sidewheelers ply the river, and villages on either bank present fine examples of Steamboat Gothic, the ornate architectural style born in the heyday of river travel. In Galena, Ill., 85% of the buildings are on the National Register of Historic Places.

At Trempealeau, Wis., the Trempealeau Hotel has offered haven to watermen since 1888. The whole laid-back region's real draw is the river itself. Steady and timeless, it makes one fine traveling companion as it rolls toward the Gulf.
