Directions to Freshwater East

Hi folks.  Just arrived at Pembrey CAMC site this afternoon.  We're here for a few nights before moving on to Freshwater East.  Assuming I can get to Kilgetty without a problem, any recommendations for which way to go to get to the,site at Freshwater from Kilgetty.  There may, indeed be a recommended route in the handbook (which is currently at home), and (unless I am looking in the wrong place) I can't find any recommended routes on the websits.

Taking into consideration this is only the third time I've taken a 8ft wide twin axle out...  I would appreciate the experience of those who know the route...

Thanks in advance.
