Hi Stevie. Nearest thing I know to the big site in Estartit is Camping Cabopino. A friend has an Atlas mobile home on site, and is very pleased with his lot.
I've looked round the complex a few times now, and I can understand why he rates it so highly. Very professional set-up, good security, well-priced restaurants, and the lovely beach at Cabopino just a six-minute walk away.
Most of the accommodation is privately owned, but holiday rentals are available, too.

My father in law stayed on the cabopino site for a few weeks last summer with his mobile home and thoroughly enjoyed it.

I was impressed when I went to visit.

Hi
We have a great Park about 45 mins from Malaga near the lakes and in the mountains free hold plots available as well as leasehold.
Quiet safe site and a lot cheaper than living on the coast e-mail me for information
