Walk this way. Why wouldn't you?

Keep your eyes peeled for red kites soaring above the common in search of carrion to feed off. These masters of the air currents, twist and switch their forked tail and long wings to glide effortlessly. Other wildlife to listen out for and spot in spring and summer are larks, wheatears and stonechats as they busy themselves with finding mates, nest building and rearing young. As you stand on the magnificent vantage point of Twyn y Gaer, with its widescreen views of Pen-y-Fan and Corn Du, the Black Mountains and the river Usk snaking below, give a thought to those who lived in this hillfort during the Iron Age. The nearby 19th century church dedicated to St Illtud was demolished in the 1990s but this Celtic Christian missionary’s name lives on in the common.

Remember to:

  • take all your litter home,
  • keep your dog on a lead – because sheep and ponies regularly graze Mynydd Illtud Common.
  • not to light fires,
  • not to camp.
