Hello and welcome!
Well, the bus is not a great option indeed , but...the journey from Malaga to Benalmadena by bus
is not that large, it can takes up to 20 minutes, and the waiting time at the bus station is short as it is the first bus stop.
Another option is to use a taxi from Malaga to Benalmadena
, or the train if your destination is at Arroyo de la Miel (where the train stop is)
Hope to be of help!
