Carn Ban is situated in the southern part of Arran, and a walk of 4 miles (6 kilometres) is required to reach the site.^[1] It is on a steep south-west facing slope in a forest clearing partly covered in grass.^[2]

It is considered as one of the most famous of the Neolithic long cairns of south-west Scotland.^[1] It is of a type found across south-west Scotland known as a Clyde cairn.^[1] It is trapezoidal in shape,^[1] with a semicircular forecourt at the upper northeast end.^[2] The forecourt has an entrance leading into a long chamber divided into compartments by cross-slabs, similar to the arrangement at Torrylin Cairn, about 3 mi (5 km) to the southwest.^[1] The chamber of Carn Ban is 30 metres long and 18 metres broad.^[1] The tomb was excavated in the late 19th century, but the only finds were a flint flake, an unburnt fragment of human bone, and a pitchstone flake.^[2] The site has been designated a scheduled ancient monument by Historic Environment Scotland.^[3]
