Mynydd Illtud is an extensive stretch of undulating common land owned and managed by Brecon Beacons National Park Authority. Sheep graze the pasture developed on thin soils which overlie rocks of the St Maughan’s Formation of the Old Red Sandstone.
An Iron Age hillfort is perched atop Twyn y Gaer at the north end of the common. Pillow mounds adorn its slopes. There are panoramic views over the Usk Valley to the north whilst the Brecon Beacons form a spectacular backdrop to the south.
Traeth Mawr and Traeth Bach are important wetland wildlife habitats and their peat deposits contain a valuable record of the climate of south Wales since the Ice Age.
