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!
