Carrauntoohil is the highest mountain on the island of Ireland, reaching 1,038 metres (3,406 feet). It stands in County Kerry on the Iveragh Peninsula and forms the central mass of the MacGillycuddy's Reeks. The peak dominates the surrounding landscape and is a well known destination for hillwalkers, climbers and visitors to southwestern Ireland.

Name and significance. The mountain's Irish name is Corrán Tuathail, commonly anglicized as Carrauntoohil. The name is usually rendered in English as a version of that Irish form. As the highest point in both County Kerry and the island, the summit is a notable reference point for geography, recreation and local identity.

Geography and geology

Carrauntoohil lies at the heart of a rugged ridge system that includes neighbouring summits such as Beenkeragh and Caher. The range was shaped by ancient geological processes and later sculpted by glaciation; rock types are dominated by Old Red Sandstone and related sandstones and shales. The terrain features steep corries, rocky ridges and deep glens that release water to streams and lakes below.

Routes and recreation

Many walkers reach the summit by marked paths, but conditions can be demanding. Common approaches include the Devil's Ladder route up from Hag's Glen and steeper ridge routes used by more experienced mountaineers. The full ridge traverse of the Reeks is a classic, longer outing that requires fitness and scrambling skills.

  • Devil's Ladder — the most frequented ascent, involving steep, loose ground.
  • Heavenly Gates and direct ridges — more exposed and technical in places.
  • Reeks Ridge Traverse — a long, rugged route linking multiple summits.

Safety and conservation. Weather in the area changes rapidly and mist, wind or rain can make navigation difficult. Hikers are advised to carry maps, compass, appropriate clothing and to check local conditions. The hills are important for wildlife and upland habitats, and visitors are encouraged to follow established paths to limit erosion and disturbance.

Notable facts. From the summit there are extensive views over County Kerry, the Atlantic coast and neighbouring mountain ranges on clear days. Carrauntoohil remains an enduring landmark for outdoor recreation and for those interested in Ireland's physical geography.
