From Irish Climbing Wiki
On the south-western side of the island is an impressive crag, up to 100m in height, which can be clearly viewed from a promontory opposite.

T. Ryan & K. McDonald July 1991.
From the vantage point of the promontory a thin blank groove can be seen on the lower R-hand side of the crag. The route starts up this and continues up the slab above.
Access is by abseil (nut, spike and Friend belay) down to ledges below the base of the groove.
1. 20m Climb the groove to a confined spike belay on the R.
2. 25m Move L about 5m and climb directly up the slab above to belay on a diagonal crack.
3. 25m Climb L-wards up the crack and then directly to the top.
