The southernmost of two round cairns located on gently-sloping, east-facing ground above Nant Paradwys at 345m above sea level.
The cairn is a stony mound measuring about 5m in diameter though its shape has been distorted by robbing spoil which has been deposited against the cairn on its west side making it seefrom north north-west to south south-west) by 0.66m wide internally and 0.5m deep. The broken capstone appears to have fallen inside the cist. A narrow footpath passes close to the cairn on its uphill, eastern, side.

Dense bracken cover prevented the cairn from being seen in summer but it was clearly visible when visited in late winter.
