The south of Spain is a wonderful place to explore in a hire car. There are plenty of sites within a reasonable distance form Seville which are well worth taking the time to visit.
One such place worthy of your attention is Carmona. Carmona is a twenty five mile drive from Seville. It is a traditional Spanish town with some fantastic places to eat out, unique places to shop and excellent hotels should you decide to stay the night.
Just five miles outside Carmona you can pay a visit to Santiponce which is home to a stunning amphitheatre. The city of Cadiz is also a short drive from Seville in your car hire and makes for a nice day out.
It seems there is always some event or festival happening within Seville or its surrounding regions. The Feria de Abril festival takes place in the spring and features lots of fun events such as flamenco dancing and bull fighting.
