This fort occupies the rocky headland on the W side of Lagavulin Bay. Irregular on plan, the wall is best preserved where it blocks the deep gullies that pierce the outcrops, probably originally measuring about 2.5m in thickness, and in one gully on the NE still standing 1.1m high in five courses with pinnings. In another gully on the NW it is rather thicker and there is also evidence of a medial wall-face within the thickness of the wall. The interior measures up to 92m from E to W by 55m transversely (0.37ha), and the entrance is probably in a gully on the N. Apart from the marker cairn on the summit, there are traces of later cultivation plots and lengths of wall within the interior, but there is also a robbed circular structure measuring some 12m in internal diameter.

First discovered by Frank Newall (Newall 1963), it was surveyed by the OS at 1:2500 in 1979, and in the same year surveyed by RCAHMS for the County Inventory of Argyll (RCAHMS 1984, 77, no.130).

Apart from a modern marker cairn, there is a robbed circular structure about 12m in internal diameter within the interior and several lengths of more recent walling.
