The site, known as ÇSlippery Island' is located c.1.3km SW of Bunmahon Village on the SE coast of Co. Waterford. It can be described as a narrow, eroding headland (Wth 6.2m) projecting c. 80m SW from the mainland. It is defended at the neck by a bank (Wth c. 3m; int. H 1.1m) standing immediately within a shallow depression or ditch (Wth 7.8m; ext. D 1.2m; int. D 2.2m) running for c. 5m in an E/W direction. Evidence for a second bank (Wth c. 2m; int. H 0.85m) is also recorded inside the first, and there is a causeway (Wth 2-2.4m) across the ditch. The interior is very narrow and there are no recorded features.
