The second trig-surmounted cairn of the day, The Beacon is less impressive than Gelli Hill cairn. It’s quite reduced and low, but it does boast similarly expansive views to many of today’s other sites, especially to the northwest where Llandrindod nestles in the valley below. Carregwiber fort can be seen, and the Radnor Mountains provide the backdrop to the northeast. It would have been a fair size, judging by the footprint and stonework protrudes here and there through the grass. Access is easy, a footpath leads straight to the cairn across a single field from the road. I don’t stay long, but head on to Little Hill VII.
A 17m overall diameter circle of earth and stones upon a rocky knoll, formed by a bank 4.0m wide to the N, elsewhere by scarps. Stones are said to have been brought here 'for luck' and a 4.0m diameter stony area surrounds the Os triangulation pillar within.
