There's also a track called 'Cartagena'. Close to Murcia (popular airport with connection to Belgium), little bit like Almeria, also lot of people go there to do some wintertraining.
The circuit is used for British Superbike winter testing and also by a lot of magazines for track testing because the weather is good almost all year round.
It is well worth a visit and you can combine your holiday with track days, time at the beach and inland is where the "Spaghetti Westerns" were filmed - you can tour the "Western" locations by Jeep.
