From Pembroke take the B4320 west. The burial chamber can be seen in the middle of a field to your left just before the road takes a sharp turn south towards Castlemartin.
As Kammer has said, there is no public access to the chamber and it is two fields over. I couldn’t see the unfriendly message or barbed wire on the field gate but you are sure to be seen if planning a ‘sneak’ visit.
Best bet is to either ask for permission (from whom I don’t know) or do what I did and have a look from the road. Even without the aid of binoculars the fallen/slanting capstone was easy enough to see.
Worth a look when in the area.
