During the summer holidays direction Pyrenees I had the chance to visit some confluence points.
On that trip we passed the region "Bourgogne-Franche-Comté" with the CP 46°N 4°E in it. From the city of Roanne I followed a very straight road, named "Route de Villemontairs", direction south west. Around 4 km after the end of the city the location of the CP was reached.
I parked the car opposite a car scrap disposal. Luckily they didn't take mine while visiting the CP. The confluence point is located on a fenced pastry. The fence is made of barbed wire, some nasty brushwood, and a ditch. But at luck I found a good approach around 100 m away from the main road, by taking a smaller road direction north, and could pass the fence quite easily there. This small road is signed as a one-way road except bicycles. From that point I had to walk back around 80 m direction main road D53 and found the exact location very soon. From the CP I did a photo from the junction to road D203. Soon the trip continued westwards.
