Alternatively, we propose an even simpler solution - A Tour of Paris and a cruise on the River Seine. You can leave Dieppe station at 8 a.m. and arrive in Paris at 10.10 a.m., changing trains in Rouen, but check the times on your chosen day. http://haute-normandie.ter.sncf.com
Leave the Gare Saint Lazare from the main entrance, turn right and walk about a hundred yards down Rue du Havre. Take the first left, Boulevard Haussmann where you’ll find the Galeries Lafayette and Printemps department stores. Around 12 noon start to look for a restaurant – it’s best to be early.
Go back towards the station and try Mollard, one of the best-known brasseries of Paris, famous for its art nouveau décor of the belle époque and listed as a historical monument. Alternatively find the 14 restaurants of the Galeries Lafayette Gourmet at 97 rue de Provence, four floors of food and fine wines at all prices and of all kinds. A feast for the eyes even if you don’t buy!
Visit the Café de la Paix, the most famous Paris café (but possibly also the most expensive) known for its mille feuilles and extraordinary ambience.
From the Place de L’Opéra pass the famous jewellery shops in Rue de la Paix and cross the Place Vendôme with the Ritz Hotel on your right, then turn left into Rue Saint Honoré. If you haven’t had lunch yet a choice of two bistros, Le Rubis and Le Bistrot, face each other in Rue du Marché Saint Honoré, at the corner with Rue Hyacinthe. You’ll find a typical bistro atmosphere and affordable prices. Continue on foot to aid digestion, - it’s nicer and quicker, (but it’s also direct on metro line 14 from Saint Lazare).
Find your way to Paris Vision, under the arcades in the Place des Pyramides with its statue of St Joan of Arc, from where you can take a coach tour of Paris to see the main sights. It lasts an hour and three quarters, returning to Pyramides, but there’s an option to be dropped by the Eiffel Tower for an hour-long river trip on the Seine. Return to the Eiffel Tower. Make your way back to Saint Lazare. On foot, going via the Seine and the Champs Elysées, it takes about 40 minutes. By taxi it takes 10-20 minutes.
By metro, including the walk to the station, you’ll need 30 minutes. Walk to the Champ de Mars station and take the RER, changing at Invalides for Saint Lazare. Use the app Visit Paris by Metro with an offline map.
Take your return train at Saint Lazare (change at Rouen, as always), arrive in Dieppe with just enough time to find a restaurant for dinner.
If you really want to visit Paris by car, choose a Sunday morning. Check in advance with the police that there are no demos planned.
