Try the Cross Park Caravan Site on the Pembroke road just passed the Killgetty roundabout. I haven't been there recently, however a friend has given it a very good report. It was quite a nice site with a friendly atmosphere when we were there a few years ago. However it seems to have improved from when we were there, if this is the case it should be an excellent site. Approx. 10 to 15 minutes drive to either Saundersfoot or Tenby from the site.
