Hi folks, I wonder if you might be able to help - we arrive in Paris for three days at 9 am at Gard du Nord. We thought we would walk from there to Montmartre for a bit of exploring before checking into our hotel (Opera area). How far a walk should we expect from the train to the Basilica? Is it uphill? If there a preferred route (i.e. more scenic/interesting), and, if not, which route would be shortest? It appears from my map that we will hit Sacre Coeur first and then we hope to explore Place de Tertre, Rue Lepic, etc before heading down to the hotel. Would appreciate any suggestions you having regarding a walking route and places of interest. We plan to spend about 3-4 hours in the area total. I am thinking we will look around Sacre Couer but not necessaily go into the crypt or dome (as we also plan to see Notre Dame, St. Chapelle, and Dome Church during our three-day visit). Thanks so much!
