Knockboy (An Cnoc Buí in Irish, meaning Yellow Mountain) is a 706-metre-high mountain on the border between counties Cork and Kerry in Ireland. It is the highest peak in the Shehy mountain range and the highest mountain in County Cork with its summit shared with County Kerry. It is the 104th highest peak in Ireland[1]. Knockboy is composed of sandstone laid down in the Devonian period which was subsequently uplifted to form a mountain range, before being eroded into its present form by glaciers during the last ice age.
