The Iron Age Caerau hillfort is possibly the oldest man-made site in Cardi. The massive bank and ditch defences surrounded a densely populated settlement over 2,000 years ago. Recent discovery of a causeway has dated the site back to the Neolithic or early Stone Age. The site also encompasses a medieval castle ringwork and an abandoned church with a poignant tale to tell. Walk includes farmed countryside and some woodland. Good views over Dinas Powys Woods, and across Cardiff from the hillfort. Don’t be surprised by the two-note boom of rheas as we cross The Lawns.
