In reply to Gills:
Follow train signs in airport to station(3mins)Put coins in machine to buy ticket to malaga(2-3 euro) Walk onto platform,check u are on right side of the line by looking at the timetables.There are only 2 direct trains to chorro so if your flight is out of sync get off at Victoria Kent to get the connecting REnfe train to Alora(if u want to hang out in Malaga continue to Maria Zambrano).
Direct trains to Chorro leave from Maria Zambrano Malaga at 10.05 am and 4.48 pm(42mins journey as they don't stop at many stations)
If u decided on the Alora option you can get to chorro by
1.walking up the hill(u may be lucky and catch a bus at station) into town and hitching
2.phone/grab a taxi(20+euros)
3.if staying at Olive B contact Mel beforehand who wil arrange pick up(not free as is only reasonable)
4.walk 2-3 hrs
Best of luck.
