The first gas station is close to RER A station Bussy St. Georges. From there you walk south for about 1 km (you can ask at the counter) along a bigger road, which will lead you to a roundabout. You can try from there, but the gas station is just a bit more than 2 km from there. You can walk on the grass field next to the highway. The gas station is called "La Ferrière". An alternate route to reach the gas station is to walk through the industrial zone of Bussy, right south of the railway, then reach the bridge over the highway and then follow on the grass until the gas station that is quite near. This avoids walking in the grass (annoying especially in winter and when raining) and instead most of the walk will be on a road, and you will save some time.
