We visited this site in late May 2015. The directions given are a bit confusing, we were back and forwards along the A75 a couple of times before stopping and phoning the holiday park for help. The easiest way if you are travelling westwards on the A75 is look out for a roadside cafe called the TEAPOT in a layby on the left, about a mile & a half after passing the turn off for Gatehouse of Fleet. If you reach the cafe you have just passed the entrance to Drummuckloch on the right. A further 200 yards along the A75 is the entrance to Cardonness holiday park on the left. No large sign with the name & listing all the facilities, as with most parks, just a small sign with 1 word CARDONNESS.
