Carrauntoohil, Ireland's highest peak at 1039m, is most commonly climbed from the Cronin's Yard car park in the MacGillycuddy's Reeks, County Kerry, a small parking area with a modest fee and a cafe, reached via minor roads from Beaufort near Killarney. The Devil's Ladder route covers about 12km round trip with roughly 1000m of elevation gain and typically takes five to seven hours. The path from Cronin's Yard follows a farm track and boggy trail into the glacial corrie of the Hag's Glen, passing two small lakes before reaching the base of the Devil's Ladder, a steep gully filled with loose scree and rock that gains height quickly and is the most technical part of the climb; there is no formal scrambling with hands required, but the loose, unstable rock demands care, particularly on the descent. Above the gully, a wide, exposed plateau leads to the summit, marked by a large cross and metal statue, with panoramic views across Kerry to the Atlantic on clear days. There is no shade above the tree line and no shelter anywhere on the mountain. A stream in Hag's Glen offers the last reliable water before the ascent, though it should be treated or filtered. Hikers uncertain about the scree gully can turn back at the base of the Devil's Ladder, having still experienced the dramatic glacial valley.

Tips for visiting

  • The loose scree in the Devil's Ladder gully is more hazardous on the descent than the ascent; take it slowly
  • A GPS device or offline map is strongly recommended, as cloud frequently obscures the summit plateau
  • Avoid the route in high wind or after heavy rain, when the gully becomes a running stream and rockfall risk increases
  • Fill water bottles at the stream in Hag's Glen before starting the climb, treating the water first
  • Trekking poles help with stability on the loose scree sections

When to visit

An early morning start is essential to allow enough daylight for the full round trip and to reduce the chance of afternoon cloud obscuring the summit.

Accessibility

The route is not wheelchair- or stroller-accessible; it involves rough boggy trail, a steep scree gully, and an exposed summit plateau.
