Baraque de Chaalis walks

Route on a sandy path with a few hills. Passes near the memorial to the March 1974 plane crash.

This marked GR® route around the Île-de-France region (with a few forays into neighbouring departments and regions) complements its "little brother", the GR®1, by forming a circular route around Paris, generally with a slightly larger radius. It follows the same overall pattern: first, a radial section starting from Paris (more precisely from the Pont d'Austerlitz, near the former confluence of the Bièvre and the Seine), going up the entire Bièvre valley, then continuing to Villiers-Saint-Frédéric, in the Yvelines. From there, it is a circular route that loops around the Île-de-France region, close to its borders with neighbouring regions. The route passes through beautiful regions, often untouched by intensive urbanisation, regional nature parks and other protected natural areas, and takes in some architectural wonders.

Eleventh stage of the Grand Tour of Île-de-France via the GR®11, connecting Chantilly-Gouvieux station to the village of Borest, reached by crossing the Chantilly estate, the Chantilly and Ermenonville forests, with a detour through the historic centre of Senlis and, optionally, a moment of reflection in front of the memorial to the victims of the March 1974 plane crash. The route follows, more or less closely, the Nonette River, which is crossed several times. The route for this stage is almost entirely in the forest, with little elevation gain, making it a very pleasant hike, and the crossings of Chantilly and Senlis add a rich touch of heritage. This stage requires an overnight stay to avoid laborious car manoeuvres. It is therefore the first of two consecutive stages, both entirely within the Oise department, between the Chantilly-Gouvieux and Crépy-en-Valois railway stations.
