Whilst staying up in Los Boliches we got the local train service to Malaga (7 euro return) to see the sights for a few hours. This easy tour located just up from main Central station was ideal for us. Costing 18 euro for a 24 hour ticket. Took in a lot of the city and excellent views from the hills. Tour lasted 1.20hour. Some very good photo opportunities and beautiful buildings. I would recommend this tour if your short on time as covers quite a lot of the city.
Plenty of places to get off and visit if you have the time.
Only bug bear was cost I think 18 euro was a little high. My opinion.
