With abundant snow, these are enjoyable Winter climbs. Ice axe and crampons essential.
Drive to Cronin's Yard, in Beaufort, outside Killarney. Hike up the main route towards the Devil's Ladder, taking the turn for O'Shea's Gully. Cross a couple of tricky rocky steps, with some exposure, to obtain the Lough Coumeenoughter corrie. Aim for O'Shea's way - the largest and most visible of the gullies, and when close to that, take a turn up into the first gully on the Left - this is Central gully. The next gully over, Left of Central Gully, is Curved.
For Central (Grade I), Approx. 200 m scramble to gain the summit ridge, and approx. 200m more takes you to the summit. The summit ridge from the top of Central Gully is quite steep and and narrow and can be tricky in winter conditions. Curved Gully (Grade I/II) is longer - maybe twice as long, steeper, and exits very close to the summit of Carauntoohil. Caution is advised for both routes in winter conditions.
Map (Harveys McGillycuddys Reeks probably the best). Helmet, Crampons and Ice-axe for when there's considerable snow and ice.
