This fort is located about 460 m north of Ardvergnish farmhouse on the lower slopes of Beinn nan Gobhar. It occupies the summit of a rocky boss and is protected by steep slopes on the south side. However, the summit rises only 10 m above the surrounding ground on the north side and as little as 4 m on the west and east.
The fort is oval in plan, the single stone wall surrounding an area measuring 39 m by 25 m. The wall varies between 2 m and 4 m in thickness. Numerous stretches and single stones remain in place in both the inner and outer surfaces. The core material stands 1.25 m high. The entrance is on the north-east side and is 1.5 m wide.
On the south-east side a relatively recent enclosure wall crosses the fort wall.
