We are thinking about maybe renting a car for a day while in Tarifa. The more I read about the Roman ruins nearby in Bolonia, the more I want to see them and I don't think we can use public transportation to get there. We also have two small children so that is another consideration. Is it possible to rent a car in Tarifa? Or maybe even take a taxi from there to Bolonia? Though it would have to be one that could get a car seat for a 3 year old....any suggestions?
