Changes

There is a bus stop just outside the metro station San Cristobal (on line 3, or the "yellow" line) that is good to hitch from (make sure you're on the right correct side of the road). There is nowhere else to pull over for several kilometers back toward the city. This same road (''Av. de Andalucia'') leads South, toward the entrance to the ''Autovía del Sur'' highway, which goes to Córdoba and Algeciras.Not far from the entrance to the ''autovía'' (maybe only about 5 or 10 km down) is another petrol station. So, you don´t even need to find a ride that is going very far from this point, because you can simply ask to be dropped at the next petrol station on the Autovía del Sur.
