Dürnstein, Austria</h4> The traveler: Michael Guerriero, author of the guidebook Party Across America: 101 of the Greatest Festivals, Sporting Events, and Celebrations in the U.S. The place: Backed by striking mountains, Dürnstein's winding cobblestoned streets and homes with steep, red-tiled roofs and window flower boxes look plucked out of a fairy tale. Sections of the fortified walls remain intact, and the baroque church's blue-and-white clock tower is inverted in time (when it's 3 p.m., the clock reads 9). A crumbling castle fortress rewards those who make the 30-minute hike up to it from Dürnstein with marvelous views of the Wachau valley. Its terraced vineyards yield crisp, dry Rieslings and Grüner Veltliners. In early April, the landscape erupts in pale-pink blossoms, and prized apricot fruits turn up in strudels, pork dishes, and Marillenknödel-traditional apricot dumplings rolled in butter-toasted bread crumbs.
