Dunchraigaig Cairn is a Bronze Age burial cairn dating back to around 2000 BC. The monument is circular, with a diameter of about 30 metres. It rises to a height of 2 metres and contains three inner chambers. Although located in Kilmartin Glen, it is not considered to be part of the primary linear alignment of graves.

Approaching the cairn, the most notable visual feature is the exposed southern chamber. This is visible beneath the capstone courtesy of the missing upper wall and is easily mistaken for an entrance portal.

In 2021, it was announced that a number of prehistoric animal carvings had been identified at Dunchraigaig Cairn. These are located under the capstone and include two red deer with fully grown antlers. Thought to be between 4-5000 years old, these are the only known carvings of this period to depict animals in Scotland.

Situated in a copse of Victorian-era trees adjacent to the main road, Dunchraigaig Cairn has the feel of a little fairy glen set off slightly from the mundane world. Sadly, the rock art was yet to be discovered when I visited, so I'm unable to say how recognisable it is to the casual eye. A path from the site leads off to the nearby Ballymeanoch alignment of standing stones.
