On Koekohe Beach at Moeraki, over 50 unusually large perfectly round boulders are dotted along the beach, singularly and in clusters, the biggest approx 7 tons and over 2 metres in diameter.
They make such an impressive site the area has become a popular tourist attraction.
Originally formed on the ocean floor millions of years ago, the boulders have been exposed through erosion of the shoreline and coastal cliffs.
While in the area, be sure to check out the equally famous 'Fleur's Place', a rustic restaurant, café and bar situated right on the waterfront at the old jetty. They specialise in serving fresh fish and seafood straight off the local fishing boats.
Moeraki is on the east coast, 30km south of Oamaru and 70km north of Dunedin.
