Jo (Audrey Hepburn) is a New York bookseller taken to Paris for a fashion shoot by the photographer Dick (Fred Astaire). Start at the Louvre, where she runs down the Winged Victory staircase in a red dress. Outside, the Carrousel arch, where she poses with balloons in the rain, is three minutes away, and the Pont des Arts, where she poses fishing from a boat, is under 10 minutes.
In the song 'Bonjour, Paris!' the three characters each tour the city on their own. The magazine editor Maggie's part fits in one short walk: the Ritz, Rue de la Paix and the Opéra Garnier are each about five minutes apart. On another day, go north to Gare du Nord, where Jo poses as Anna Karenina among the trains, then walk about 15 minutes up to Sacré-Cœur. Save the Eiffel Tower for the end: the song ends at the top, where the three meet again.
Versailles is about 14 km out: take the RER C to Versailles Château Rive Gauche for the scene where Jo releases a white dove by the Latona fountain. Up at Sacré-Cœur, the places of Amélie are just a few steps away.
