Campsites In Spain

Can it be for families and please in Northern Spain

There are some good places around Llanes, Asturias. There are fabulous beaches around there, especially in Playa de Barro only a few miles from the city. Also another great place is Celorio.
Here's some info on the campsites there.

What do you mean northern Spaina Northern Spain covers nearly 2000 km from Galicia to Catalonia. I know some places in northern Catalonia, but I do not know if that's what you are looking for.

You should be more specific.
