A fine summers day on Beachy head, the highest point at around 175m of the seven sisters, a string of pearly white sea cliffs in the south downs.  We walked along the tops to Birling Gap, had a beer, as you do, then meandered back along the rocky shore, passing the 43m high Beachy head lighthouse en-route.  A steepish climb at the end brought us to the car park and the waiting ice-cream van atop Beachy Head.
