Much of the Talgarth area lies within the Brecon Beacons National Park, the eastern boundary of which follows Offa's Dyke. The Black Mountains are carved from fluvial sandstones - the red-brown Lower Devonian Brownstones and the green and purple Senni formations. Interbedding of mudstone between the sandstones have produced stepped valley sides which display the geology spectacularly.
