One of Ireland’s most famous long-distance trails, the Wicklow Way stretches over 130km from Dublin’s southern suburbs to Clonegal in County Carlow. Hikers pass through lush forests, remote uplands, and the stunning Glendalough Valley—home to ancient monastic ruins and mirror-like lakes. You can do the whole trail over several days, or dip in for a scenic day hike.
