Corrigasleggaun, Mountain summit in County Wicklow, Ireland.

Corrigasleggaun is a granite peak reaching about 790 meters in the southwestern Wicklow Mountains, forming part of the Lugnaquilla massif. The summit is marked by a stone cairn and sits above rolling slopes that descend toward surrounding valleys.

The name Carraig na Sliogán, Irish for 'Rock of the shells', is the only historical record attached to the peak; no founding date, owner or event is documented. Its documented standing comes from lists: it ranks 35th on the Arderin scale and 45th on the Vandeleur-Lynam scale of Irish summits. It stands in the southwestern Wicklow Mountains as part of the Lugnaquilla massif, whose 925 m summit is County Wicklow's highest.

The Irish name Carraig na Sliogán means "Rock of the shells", a reference walkers still note when reading the summit on maps. The peak stands at the head of the glen of the Carrawaystick River, whose corrie lake, Kelly's Lough, lies near the top. It is counted as the 35th-highest peak in Ireland on the Arderin scale.

Climbers should carry detailed maps and navigation tools since the summit can be hard to locate in poor visibility and trails are not clearly marked. Weather conditions change rapidly and winds are often strong, so proper mountain gear is important for safety.

Kelly's Lough, a glacial lake in a rocky corrie near the peak, sits in a dramatic mountain hollow that many hikers pass without noticing. The mountain also marks the source of the Carrawaystick River, which flows down the eastern slopes and cuts through the landscape below.
