This is a handy stopover site if you are heading for the South of Spain. A little on the expensive side at €23/night March 2018 (Including EHU and WiFi). You can get a discount if you have a 'Camping Key Card'
We have used this site when going to Benicassim. We paid 28 Euro it is expensive but at least those who have Caravans can stay hooked up overnight. We came off the main road before you did and went through the centre of Zaragoza, which is not that bad if you have a good satnav. There is a Garage just around the corner on the way out. If you go in the winter bear in mind it is so we were told one of the coldest places in Spain. The other one we tried which is another 3 hours on is Camping Altomira at Navajas. It is up quite a steep hill and once you enter the site again it is steep. the pitches are terraced which sounds good but some have a kerb nearly a foot high. The motorhome in front of us damaged his rear end trying to get on the pitch. We had to use a ramp to get on the pitch. Altomira is not one I would recommend.
