There is no enclosure wall to mark the boundary, no obvious barrier between the burial ground and the surrounding field, yet the site contains the remains of a small oratory, a hut, a leacht, and a cross-slab, all gathered within a low rectangular enclosure. A leacht is a small cairn or stone monument associated with early Christian devotion, often marking a place of prayer or commemoration, and its presence here, alongside a cross-inscribed slab, suggests this was once a place of deliberate spiritual purpose rather than simple expedience.

Beginish is a small island wedged between Valentia Island and the Kerry mainland at the northern end of Valentia Harbour, rising gently from its more fertile south-eastern portion towards cliffs at the north-west. The children's burial ground sits roughly 200 metres north-west of Cruppaun Point, on the island's southern shore. It is not an isolated feature in an otherwise empty landscape; some 900 metres to the north-east lies a separate settlement complex that was excavated by O'Kelly, pointing to a more substantial early medieval presence on the island than its current quietness might suggest. The site appears on the second edition of the Ordnance Survey map as that L-shaped area at the northern end of a field, the southern end of which remains open to the sea, a configuration that gives the place an oddly provisional quality, as if the boundary between the sacred ground and the Atlantic were always understood to be permeable.
