The mill, Villiers-sur-Morin
The essentials
Getting here
Transilien line P from Paris-Est to Esbly, then the T14 tram-train (towards Crécy-la-Chapelle) to Villiers-Montbarbin station. The starting panel is just outside the station.
Take the A4 motorway, exit Crécy-la-Chapelle, then follow signs to Villiers-sur-Morin. Parking at Villiers-Montbarbin station.
A phone is all you need, nothing to install. Wear comfortable shoes: the trail follows the village streets and the banks of the Grand Morin.
The starting points of the Crécy-la-Chapelle, Coulommiers and Luzancy trails will be announced when they open.
