Hi Robbo,
This site has pitches in among the gorse bushes.The beach is really lovely....flat and sandy but with lots of rock pools for the children to explore.There is a light house at Drummore and on a good day you can supposedly see N/Ireland.
Port Logan is nearby....a very tiny village,but with a lovely liitle harbour.There are really good botanical gardens nearby as well.Portpatrick is worth a visit,and the children may want to watch the ferries leaving for Ireland from Cairnryan and Stranraer.there is plenty to do and see,but as always....you need good weather.
Part of the site is being refurbished this year,so will not be running to capacity until later in the season.
Enjoy your holiday.
