Follow my direction notes for the Cairn Ring.
Once you have parked by the yellow grit/salt bin keep following the field surrounded by a stone wall (on your left) until you reach the SECOND metal field gate. From here you can see the burial chamber up the hill, towards your left.
The site comprises of several large, flat stones with the capstone propped up at the front by the other stones. Under the capstone were many smaller stones.
