Traveling by car is the best way to explore South Spain, as it allows you to reach all the major destinations in a convenient and time-efficient manner. Expect to pay around €100-€150 for five days car rental, and add extra time for parking and tolls.
If you have more time, add a day trip to the picturesque town of Nerja or the stunning white village of Mijas. On the other hand, if you're short on time, skip Ronda and spend an extra day in Seville or Granada instead.
