The Costa del Sol lazily stretches out along the southern Mediterranean coast of Spain. Not really committing to the industrious ambitions of Barcelona or Madrid, the coast is a land of perpetual siesta, where work orders are responded to with a simple "manana," and beaches gradually disappear into salty azure waters. It is the kind of place that convertibles were invented for.
To tackle it in 3 days would be a shame, but better than having not visited at all. To really cover the ground necessary along the Costa del Sol, an automobile is necessary. Luckily, car rentals in Spain are very affordable, as cheap as 15 Euros per day. Inexpensive flights also abound from all over Europe on Easyjet and Ryanair. It is possible to fly to Malaga for under 20 U.S. dollars from Barcelona round-trip. Once you have arrived along this golden coast of white villages and luxurious beaches, there is much to do and see.
