To go hiking, you don’t need to rack up hours on trains, in cars, or even at the airport. Only your Navigo pass will do, provided you know the best spots, trails, forests and regional parks for hiking in Île-de-France.

In Île-de-France, the Grand Morin mostly runs through the Seine-et-Marne department, where the river winds through picturesque villages such as Crécy-la-Chapelle or Villiers-sur-Morin, delivering you to the heart of a lesser-known Seine-et-Marne—greener, quieter, more in touch with nature. So, from Guérard to La Celle-sur-Morin and other spots in the Brie country and the Grand Morin Valley, set off to discover these trails accessible to all, and above all, with just a Navigo pass only.

In a day, a Wednesday afternoon, or a full weekend, the Grand Morin Valley has now established itself as one of Île-de-France's premier hiking destinations.

Obviously, always head out with a .gpx track of your hiking route, a spare battery (in case your phone dies), at least 1.5 liters of water per person, something to eat, protection from rain if needed, and sunscreen (sunglasses and a hat) in summer. Have a wonderful stroll in Seine-et-Marne and in the Grand Morin valley!
