If you are in Paris and would like to go somewhere for a weekend, I may suggest you a couple of charming towns in Lower Normandy – Trouville-sur-Mer and Deuville. You enjoy there a beautiful beach, amazing seafood, refreshing cidre on a hot day and a wonderful atmosphere of Atlantic ocean (English Channel). It’s a bit hard to get a hotel on a short notice, then you can stay in Blonville-sur-Mer, which is just 10 minutes from Trouville/Deuville by a local bus.
To get there take a train from Paris Gare St. Lazare in the direction of Trouville/Deuville. It takes about 2 hours to get there. On Sunday you’ll find local farmers markets both in Deuville and Trouville, so don’t miss a chance to enjoy real French delicacies!
