Hi Colliepal,
The Caravan Club show photos of a few Cl's in that area
1.P483 under the heading New Abbey ( very bottom of the page ) Landis Farm,which looks lovely.
2.P484--under Stranraer.....Greenloch House....this looks like paradise.
Haven't stayed at any of these,but have chosen to keep them on our list.
3.On the West Coast....Page 484 under Sandhead is a beautiful little hamlet called Port Logan.Muldaddie house CL sits high up with wonderful views over the bay.Went to see this place and thought it looked great....although might be tricky when a gale blows in.
I think the CL at the distillery which Emmerson mentioned is in fact a CS.
