In the evening we took ourselves north to Rapahoe, recommended by people we met at Okarito. The scenery, as you can see, is spectacular from the beach, the great fraying of rocks to create off-shore reefs beginning hereabouts.
The camp site was a bit of a bust; we went in as we wanted showers. But the two showers were rubbish. Only one could be used at a time, very little pressure and minimum privacy from the living/dining space. Which was, incidentally, well-colonised by a large German group. There is an astonishing number of Germans travelling here this summer, and they are as noisy as Americans! (Humph: xenophobic moments from both of us.)
The only good thing was that Pip saw a weka as she lay in bed in the morning.
So if you go to Rapahoe in a van, drive down by the hotel (most southerly turn off on the beach side of the highway) and free camp on the side of the beach.
