Edit 2018: this is not correct! It is much longer 30 min on S3 train till Holzkitchen than this says, I could not walk to Foching town find this supposed short route in July 2018 and it wouldn't even make sense with a Schmiedstrase turn left walk till concrete rouds end / cross. Petrol station is on the mapright Around 5 km walk  OR  30 min on S3 train till Otterfing. You will go from Walk in the Otterfing same direction your train station south and was going for 200 meters then turn left over the bridge as stated then take a right on a path . Follow this road (Kreuzstrasse) for 2.5km through fieldsand a forest until you reach the Autobahn. There are several dirt roads going left through  Turn right just before the field, take one and you will eventually arrive at road goes under the forest and find a signautobahn. You walk through Follow this for a ways and end up in another field with more paths you follow a bit north through a cow farm with road past the solar panels on until the entrance of another tunnel under the roof that eventually leads autobahn, from here you should be able to see the gas petrol stationahead. With a pack  Cut through the field to reach it (you don't need to jump any fences, to enter walk takes about an houraround the fence, to exit use the gap where the fence changes design). Around 5 km walk
