Callanish IV is around two miles southeast of the Callanish Stones, about 180 metres west of the unfenced B8011 road.
The stone circle forms a pronounced oval measuring 13.3 by 9.5 metres. Only five stones currently stand, but there could have been as many as thirteen. The stones range in size from 2 to 2.7 metres.
In the centre is a dilapidated cairn. A small slab, 60 centimetres high, is set on edge within the cairn.
