Composite description from Canmore:
Dalcross Mains, a Clava passage grave, has had most of the cairn material removed flush with the top of the chamber which is almost 12ft diameter. The kerb is 40-42ft diameter. One monolith survives with a slab to the west of it.
It has been quarried in the NW segment. 10.0m NE of the latter, a further stone, 0.7m high, has possibly been displaced from the inner kerb. Two portal stones remain in the SW, and the outline of the central chamber may still be seen.
