South Cuckoo enclosure measures approximately 100m across and is sited on the south facing slope. The eastern end is squared, while the western end is curved. The site appears to enclose a spring from which flows (or used to flow) a small watercourse. The enclosure is partly open on this side. There are faint earthworks of ridge and furrow crossing the whole site.

The site was identified during RCAHMW aerial reconnaissance in 2000.
