Changes

There's a small but decent gas station in the suburb of Ospedaletto. Get here by bus number 16, get off at 'Malpighi 2' and walk across the fields. You can continue walking straight until you hit the field, turn right and left immediately into a track. Follow it through the field to a road where you turn left and follow straight until you hit the highway (don't cross it). here you turn left, go under the bridge and through some gardens until you hit the gas station where you need to hop the fence. There might be an easier and more accessible way to get in, but that's the information that is available so far :-)

Take the bus LAM rosso (red line) to the Aurelia bus stop (it's in an opposite direction to the airport so different starting bus stop!). From there go further about 100m until you reach a roundabout and SS1 route. After the roundabout go straight. There is a turn right from the route to the hotel/restaurant where all the cars can easily pull over. Hitchhike there! It took me about 15 min to get a ride to Genoa.
