Carrantoohil is the highest mountain in Ireland, standing at above sea level. It’s a challenging but rewarding climb for experienced hikers, offering stunning views of the surrounding landscape and the lakes below.

The most common route to the summit is via the Devil’s Ladder, a steep and rocky gully that requires some scrambling and care. Alternatively, you can take the longer but less steep Zig Zag route or the more scenic Brother O’Shea’s Gully route.

Whichever route you choose, make sure you are well prepared with proper clothing, footwear, map, compass, and water. You can also book a guided hike with a local company such as Kerry Climbing if you prefer.
