hi folks pretty straightforward when you leave airport follow signs for murcia this takes you onto motorway ap7 follow this for 20 mins or so it goes into 3 lanes but then splits into 2 look for a repsol garage on the right and just after move into middle lane and follow murcia signs after another 20 mins you come into city of murcia keep in right lane then take exit for Almeria/Granada.
follow this road till you see signs for Mazarron its just after a sign for el pozo factory be careful this exit has A and B exits you want the B exit then follow the signs for Mazarron this will take you right past the exit for Condado de Alhama.
Hope this makes sense to you contact again if you have any problems!
