On the Coast Road (SH6) between Greymouth and Barrytown the road runs for a short stretch beside a long, deserted West Coast beach. To reach the pebble beach from the road you must scramble down a short embankment, carefully picking your way between wild blackberry bushes. Waves rush up the beach and then recede, leaving behind newly wetted pebbles that glisten in the sunlight. Overhead on the day of our visit there were jet trails that converged towards the horizon. Outflowing water from the previous wave left a trail of rivulets that seemed to converge on the same distant point.
