Five of us set off from the Hydro car park in wet & windy conditions. We walked up the concrete road and went to the East (left) of Loch Com Lothair and Lough Eagher on relatively flat ground. At the back of the latter lake, we ascended the Black Mare gully – first gradually then more steeply. We then went to the cross on Carrauntoohil. Weather conditions dictated that we return over Caher. It was only only when we were quite far down on Caher that conditions, and visibility, improved.
