This is the saltmarsh - the main road from the Airport to Torrevieja runs right through it, but note the warnings about being careful when parking :eek!::

Thanks for correcting me Mark, I've been trying too remember the name of the place all night, as I said it's been over 10yrs and probably changed alot, reading your link certainly brought back alot of memories, and yes be careful with parking, very dangerous and a very fast road.
