I found the Moeraki Boulders fascinating. Unfortunately I had a grey day and rain when visiting, and next time I will make this spot an overnight stay and hope for a good dusk and dawn. I’d also do a bit of research next time and try to be there at low tide. The boulders even have their own website at http://www.moerakiboulders.com/. (Explanatory extract from the website in italics below.)
“The Moeraki Boulders are a number of huge spherical stones, found strewn along a stretch of Koekohe Beach near Moeraki, a small settlement just south of Hampden on New Zealand’s Otago coast. These boulders are grey-coloured septarian concretions which have been exposed through shoreline erosion from black mudstone coastal cliffs that back the beach. They originally formed in ancient sea floor sediments during the early Paleocene some 60 million years ago.
The boulders weigh several tonnes and are up to three metres in diameter.
Maori legend tells that the boulders are remains of calabashes, kumaras and eel baskets that washed ashore after the legendary canoe, the Araiteuru was wrecked at nearby Shag Point (Matakaea).”
When you visit, beware of the trap of using the walkway from the visitor centre shop and cafe – it costs $2 pp. If you drive 300m south you can use the free public carpark and walk back for free!
