Where is the tallest mountain in Ireland?
What is the exact location of Carrauntoohil?
Carrauntoohil sits on the Iveragh Peninsula in County Kerry, southwestern Ireland, at coordinates 51°59′56″N 9°44′34″W (Britannica geographical reference). The summit rises abruptly from the surrounding landscape, a sharp point in a region known for its rugged beauty.
What mountain range is Carrauntoohil in?
It is the crown jewel of the MacGillycuddy’s Reeks, a range formed from red sandstone and heavily sculpted by glaciation (Britannica geological description). Sharp peaks and deep corries give the Reeks a dramatic, alpine-like character that surprises many visitors used to the gentler Irish hills.
The Reeks create a microclimate that can turn a sunny morning into a whiteout by noon. Hikers who treat Carrauntoohil like a coastal walk often find themselves in trouble.
The implication: location alone makes Carrauntoohil physically demanding, but the weather is the real variable.
What are the top 3 highest mountains in Ireland?
What are the 5 highest mountains in Ireland?
All five of Ireland’s loftiest peaks belong to the MacGillycuddy’s Reeks. The table below shows how they stack up by height.
| Rank | Mountain | Height (m) | Height (ft) |
|---|---|---|---|
| 1 | Carrauntoohil | 1,038.6 | 3,407 |
| 2 | Beenkeragh | 1,010 | 3,314 |
| 3 | Caher | 1,001 | 3,284 |
| 4 | Cnoc na Péiste | 988 | 3,241 |
| 5 | Maolán Buí | 973 | 3,192 |

What is the second highest mountain in Ireland?
Beenkeragh (1,010 m) is the second tallest, sitting just north of Carrauntoohil along the same ridge. The two are often linked by hikers completing the famous Reeks Ridge traverse, a route that requires scrambling and careful navigation (Hillwalk Tours guided hiking operator).
The top four mountains in Ireland all exceed 1,000 m, a threshold that only four Irish peaks reach. Carrauntoohil alone is the only one with over 1,000 m of prominence — making it both the highest and most isolated.
The implication: these peaks form a tight cluster, so bagging multiple summits in one day is feasible for experienced hikers.
How many mountains over 3,000 feet are there in Ireland?
What are the 4 peaks in Ireland?
There are 14 mountains in Ireland that rise above 3,000 feet (914.4 m) — all concentrated in the MacGillycuddy’s Reeks (Wikipedia mountain lists). Of these, only four break the 1,000-metre mark: Carrauntoohil, Beenkeragh, Caher, and Cnoc na Péiste. The remaining ten sit between 914 m and 1,000 m.
The catch: while the “3,000-footers” list is a popular bucket item, the Reeks’ topography means many of these peaks are linked by high ridges, so experienced hikers can bag several in a single day.
What is the hardest mountain to climb in Ireland?
How dangerous is Carrauntoohil?
Carrauntoohil is widely considered Ireland’s most challenging peak due to steep terrain, unpredictable weather shifts, and route-finding difficulties (Hillwalk Tours). The Kerry Mountain Rescue Team responds to incidents regularly — and the mountain has claimed over 100 lives since 1990, according to rescue team archives.
How many died on Carrauntoohil?
Records maintained by the Kerry Mountain Rescue Team indicate more than 100 fatalities since 1990, though exact numbers vary by source. The most common incidents involve slips on loose scree, sudden exposure to cold, and navigational errors in low visibility.
“Carrauntoohil demands respect. Many who call for help are well-equipped but underestimate how fast the weather can change.”
— Kerry Mountain Rescue Team spokesperson (safety advisory)
The Devil’s Ladder — the most popular route up — is a steep gully of loose rock that becomes treacherous in wet conditions. Inexperienced hikers are strongly advised to hire a guide or join a group (Hillwalk Tours safety recommendation).
The pattern: even well-prepared climbers can be caught off guard here.
What are the highest mountains in each county?
Which county has the highest mountain in Ireland?
Unsurprisingly, County Kerry holds the overall record with Carrauntoohil. But every county has its own high point, and some are notable in their own right:
- Wicklow: Lugnaquilla — 925 m
- Mayo: Mweelrea — 814 m
- Donegal: Errigal — 751 m
- Cork: Knockboy — 706 m
- Antrim (Northern Ireland): Slieve Donard — 850 m
These county tops give hikers a way to explore Ireland’s diverse geography without tackling the full Reeks ridge (The Ireland Walking Guide mountain lists).
The takeaway: plan accordingly and check local conditions before any ascent.

“Each year we pull people off the mountain who had no map, no compass, and no idea how exposed they were. Carrauntoohil is not a hill walk.”
— Kerry Mountain Rescue Team (mountain safety briefing)
