Images from a run out to Ailsa Craig. This c500 Million year old volcanic plug rising 340 metres (or 1,110 feet) out of the sea in the outer approaches to the Firth of Clyde is well worth a closer look. It stands about 16 kilometres (10 miles) out from the coast west of Girvan. The rock was quarried for its Blue Hone Granite to make curling stones, although the resident, Human, population have long gone, the rock is home to vast numbers of Gannets. Since the introduced population of rats has been removed, numbers of Puffins are now nesting there too. See our Pricing page for details of runs.
