Would you ever include a cemetery to your itinerary? You should with this one. Père Lachaise is the most visited cemetery in the world.
Taking the train from Gare du Nord, Amiens is a 1h15 ride from Paris. We spent one week-end with friends living and working here. It was a cloudy and rainy Saturday with almost no one in the streets. But it is winter and the weather calls for a stay-in kind of day so I do not blame them. The highlight wasn’t the number of people going around though, you cannot expect any other city to be as busy as Parisian streets, but this city has a grandeur of its own.
