Hi, coming in from A1 (not from St Abbs direction) when you approach high school roundabout, take a right along side of school, not far past entrance to gold course, there is a large parking area there, you can carry on right down to harbour, you will see a yellow barrier on you're RHS if barrier is up, nice isolated spot right over the back, I've used this a couple of times, depends on barrier situ tho??

There is only one problem at this location, there is no bridge to cross over harbour into main part of town, you would have to drive back round, when you going, I have business down there soon?
Cheers.
Ps, road to right.
