- The spherical boulders themselves — huge, near-perfect stone spheres scattered along Koekohe Beach; they’re septarian concretions that formed inside ancient mudstone and were revealed by centuries of coastal erosion, which is why they look so improbably round.
- Septaria cracks and cross-sections — many boulders are cracked open to reveal the distinctive angular veins and crystal-filled centers, giving you a peek at the internal structure that geologists find fascinating and photographers love.
- Low-tide exploration — at low tide you can walk right up to most of the boulders, clamber between them and check out tide pools and small marine life; it’s the best way to see scale and texture up close (but don’t chip anything).
- Sunrise and sunset light — the flat beach and polished stones catch

- Sunrise and sunset light — the flat beach and polished stones catch golden and blue-hour light beautifully, turning ordinary photos into dramatic silhouettes and long shadows; aim for low tide and calm seas.
- Māori legend and cultural value — the boulders are woven into local Māori stories (linked to the wreck of the canoe Araiteuru), so the site has strong cultural resonance as well as scientific interest.
- Coastal scenery and wildlife — the boulders sit against cliffs, wide sandy stretches and occasional seals or seabirds; it’s a compact example of Otago coast scenery that’s easy to combine with a short walk or picnic.
- Fragility and conservation — the boulders are eroding naturally and many are fragile; the unique thing here is seeing an ongoing natural process, so visitors are asked to observe responsibly: don’t remove pieces, and stick to paths to protect the site.
