The closest airport to Turre and Mojacar is Almeria, about an hours drive on main roads. However this is a small airport and only goes to London and a few other places.

 

Murcia airport is the next closest and much bigger. They fly to Bournemouth, Bristol and London. It is about a 2 hour drive on main roads.

 

After that Malaga, Granada and Alicante are all big airports, but i dont recommend the drive from Malaga if you are not confident driving in 'Spanish conditions' as the roads are as crazy as the drivers are. They are 2.5 to 3.5 hours drive.
