If leaving Castle Douglas on the A745 Dalbeatie Road, slow down after passing the last houses and look for a small access road on the left and pull in. this is a field access lane but there is lots of room to park at the start of it without obstructing anything. The stones should be visible across the field ahead. Walk up the lane a fie yards to the gate to the adjacent field. Walk up that one then cross into the stones field at the gate. There is probably closer access from the other side of the field where new houses have been built but this route was easy enough.
