Driving around Casares, Costa del Sol, Spain

You can stay at Casares del Sol in Costa del Sol apartment without a car, there are buses just 5 minutes walk away and a taxi rank at a similar distance so its not essential to have a car, and there are several bars and resturants within 5 minutes walk. But to get the most from a holiday in the Casares area of Costa del Sol in Spain, you should really hire a car.  It means you can explore the area much easier, up into the hills and mountains just 10 minutes drive or down along the coastal road to the various beaches dotted along the Mediterreanan Sea coast, Duquesa beach, Sotogrande beach, and onto La Linea beach at the base of Gibraltar.
And with a car you can explore the local resturants more easily. But driving rules in Spain re drinking and driving at more strict than in the UK. In Spain there is no tolerance of any drinking pre driving, zero tolerance. So becareful. The Spanish do random testing sometimes, so be warned. So if you want a drink, use the taxis.
A car allows you to really explore the Costa del Sol area of Andalucia with places to see near Casares del Sol. A day in Casares old town in the hills. A day on Estapona beach. A night out in Puerto Banus. A days sailing from Gibraltar. All these days out are very close to Casares del Sol and easily done with a car.
