Youghal has some of the best-preserved medieval town walls in Ireland, with a significant stretch still standing on the hill overlooking the harbour. You can walk the sentry walk along the upper section and look out over the Blackwater estuary toward County Waterford — a view that has changed remarkably little in centuries.
The walls date from the 13th century, with later additions, and once enclosed the entire Anglo-Norman settlement. Today's route follows the most intact surviving section, from near St Mary's Church along the hillside. A good pair of shoes helps on the uneven ground. Free to access and best in the late afternoon light.
