31-Oct-2001 -- Coming from Paris, we left the highway A11 at Luigny, and proceeded south to La Bazoche Gouet, Le Gault du Perche and Saint Agil, then south-east to Boursay, using the D40.
From there we took the small road to "Le grand Bouchet" and there, left to "Les Bailliveries" where we had to leave the car, as it was forbidden to go further if motorised!
Leaving the car 680 meters from the confluence (N47° 59.92 E000°59.52), we then followed a sunken road among hedges and meadows on the south side of the Grenne brook.
The road terminates at a small old restored farm and the end of the way to the confluence had to be done through steep meadows and across hedges.
The spot is 193 meters high in an open area with cows in the distance.
