Carbad More is a double court cairn, with the main axis running NE-SW. Both galleries are covered in thick vegetation, the south west court has 10 stones on site forming the portal into the gallery. At either end of the remains of a cairn are the remnants of two almost circular courts, each leading into its own segmented gallery. The larger court is about 7.6 m (25 ft) in diameter.
