At just 440 metres Tair Carn Isaf is a modestly sized hill, but its prominence at the western end of the Black Mountain, high above the Amman Valley, affords extensive views over central south Wales, into Powys, west to the Preselis, and over the Gower Peninsula and Severn Estuary.

Tair Carn Isaf at 460m stands at the western end of the Brecon Beacons National Park. This position creates amazing views south over the Gower and out to the Bristol Channel and west towards Pembrokeshire. There are three stone cairns on the summit, one has a trig point.
