Deep within the Cornwall Area of Outstanding Natural Beauty, the village has a popular pub, The Logan Rock Inn, a village shop, cafe and campsite with views to both Logan Rock and nearby Porthcurno.
Treen overlooks the Penberth Valley and sits about a kilometre inland from Treryn Dinas, an Iron Age promontory fort, or cliff castle.
People have occupied the impressive rocky promontory at Treryn Dinas since early prehistoric times. Flint tools have been found dating back to the Mesolithic, or Middle Stone Age, period. The local eighteenth-century antiquarian William Borlase mentions a Neolithic stone circle, although there is little to be seen of it now. The ramparts and ditches of the Iron Age promontory fort are visible, however, defending the landward part of the headland, as are the remains of stone houses within. Coins and a copper brooch from Roman times have also been found here..
At the end of the promontory is the famous Logan Rock, or rocking stone.
