Durtreint (cours d'eau) - Affluent de la Voulzie walks

This easy walk takes you past all the interesting buildings in Provins, both in the upper and lower towns, and follows the streets with the finest clusters of half-timbered houses. The circular route rounds off this urban route with a countryside detour to a few points of interest, whilst also offering views of the upper town as a whole.

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.

This is the twenty-first stage of the Grand Tour of Île-de-France via the GR®11, and the last of the three stages through Brie between Coulommiers and Provins. It is still quite long but without any real difficulty.This stage completes the crossing of Brie, reaching Provins, whose iconic monuments (Caesar's Tower and the dome of the Collegiate Church of Saint-Quiriace) can be seen from afar in good weather, marking the destination of the stage!
