We would like to propose you some hikes that we liked. Because you stay with us, we start from Baulne-en-Brie, a village in the commune Vallées en Champagne. 5 km away is the village of Condé-en-Brie, its castle and much more. Our favourite part of the Marne valley is the western part. We offer you the hikes in .pdf format during your stay. You can also find them on the following websites:
