A deep opening in a dark coastal cliff glows with rows of lanterns. Their warm light reveals the broken surfaces of the cave roof and the stepped ledges inside, drawing the eye from the broad entrance toward the smaller lights farther back. Outside, the sea and clouded evening sky remain cool blue-grey, with a narrow trace of sunset along the horizon.

Two children stand hand in hand on the wet sand, looking into the cave. The boy wears a thick yellow sweater and carries a brass lantern; the girl has long blonde hair, a dark coat and red boots. A thin wash of water curls around their boots, reflecting the lamps in small, moving streaks. They remain modest figures beside the height and depth of the rock.

The scene is built from strong contrasts of texture and light. Rough black stone frames the gold interior, while smooth wet sand spreads the reflections toward the foreground. The repeated lanterns give the cave an inviting depth, turning a quiet coastal dusk into a moment of discovery.
