As Ireland's highest mountain, Carrauntoohil is popular with mountain walkers, who most commonly ascend via the Devil's Ladder route; however, Carrauntoohil is also climbed as part of longer mountain walking routes in the MacGillycuddy's Reeks range, including the Coomloughra Horseshoe or the MacGillycuddy's Reeks Ridge Walk of the entire mountain range. Carrauntoohil, and most of the range is held in private ownership and is not part of any Irish national park; however, reasonable access is granted to the public for recreational use.

, leads down to a col where sits the top of the Devil's Ladder (the classic access route for Carrauntoohil from the Hag's Glen), but then rises back up to
Cnoc na Toinne , from which the long easterly ridge section of MacGillycuddy's Reeks is accessed.
Carrauntoohil overlooks three U-shaped valleys, each of which containing their own lakes. To the east of Carrauntoohil is the Hag's Glen (), to the west is Coomloughra (), and to the south is Curragh More ().
Carrauntoohil has a deep corrie, known as the Eagle's Nest, at its north-east face,
which is accessed from the Hag's Glen, and rises up through three levels. At the top, the third level, is Lough Cummeenoughter, Ireland's highest lake. The Eagle's Nest gives views of the gullies on Carrauntoohil's north-east face: Curved Gully, Central Gully, and Brother O'Shea's Gully.
Sometimes the term Eagle's Nest is used to refer to the small stone Mountain Rescue Hut that sits on the first level of the corrie, where the
Heavenly Gates descent gully meets the Eagle's Nest corrie.
Carrauntoohil is the highest mountain in Ireland on all
classification scales.
It is the
133rd-highest mountain, and 4th most prominent mountain, in Britain and Ireland, on the
Simms classification.
Carrauntoohil is regarded by the

Because of the dangers of the steep north-eastern and eastern faces of Carrauntoohil, the Kerry Mountain Rescue Team (KMRT) have placed danger signs on the summit, and particularly above the Howling Ridge sector (the ridge between the north-east and east faces), whose initial section can be mistaken for a hill-walkers descent route.

name.[
Paul Tempan's ''Irish Hill and Mountain Names'' notes that Carrauntoohil's Irish name "is shrouded in uncertainty", and that "Unlike some lesser peaks, such as Mangerton or ]Croagh Patrick

, it is not mentioned in any surviving early Irish texts". The official Irish name is , which Tempan notes is interpreted as "Tuathal's sickle", Tuathal being a male first name. Patrick Weston Joyce previously interpreted it as "inverted sickle", translating from the Irish language term meaning left-handed but according to PWJ, "is applied to everything reversed from its proper direction".[ From yet another perspective, one of the earliest written accounts of the mountain by Isaac Weld in 1812, calls it ''Gheraun-Tuel'',] and Samuel Lewis's ''Topographical Dictionary of Ireland'' (1837) calls it ''Garran Tual''; suggesting the first element was ('fang')—which is found in the names of other Kerry mountains—and that the earlier name may have been ('Tuathal's fang').
Ownership
The climber and author Jim Ryan noted in his 2006 book ''Carrauntoohil and MacGillycuddy's Reeks'' that the actual mountain of Carrauntoohil, including most of the Hag's Glen, is in private ownership. The freehold is owned by four families: Donal Doona, John O'Shea, John B. Doona, and James Sullivan. Their great-grandfathers bought the land from the Irish Land Commission
The Irish Land Commission was created by the British crown in 1843 to "inquire into the occupation of the land in Ireland. The office of the commission was in Dublin Castle, and the records were, on its conclusion, deposited in the records tower ...
, "paying the sum of eleven shillings and two pence (€0.70 in today's money), twice a year for many decades". Ryan's book commended the owners for providing access over the years, despite damage to their farms.
A state-sponsored report into access for the range in December 2013 titled ''MacGillycuddy Reeks Mountain Access Development Assessment'' (also called the Mountain Access Project, or MAP), mapped the complex network of land titles. Unlike many other national mountain ranges, MacGillycuddy's Reeks are not part of a national park or a trust structure, and are instead completely privately owned.
The ownership situation has raised concerns in light of the material rise in visitors to Carrauntoohil (and the range in general), and the erosion and lack of infrastructure that other state-owned sites have been able to address. In 2019 the ''Irish Times
''The Irish Times'' is an Irish daily broadsheet newspaper and online digital publication. It was launched on 29 March 1859. The editor is Ruadhán Mac Cormaic. It is published every day except Sundays. ''The Irish Times'' is Ireland's leading n ...
'' reported that the MacGillycuddy Reeks Mountain Access Forum, a cross-body group of landowners, commercial users and public access and walking groups set up in 2014 with the aim of "protecting, managing and sustainably developing the MacGillycuddy's Reeks mountain range, while halting and reversing the obvious and worsening path erosion", had achieved some success laying down new pathways in the Hag's Glen approach to Carrauntoohil; however, the ''Irish Times'' still wondered, "Should the Kerry reeks be a national park?"
Recreation
Visitors
Separate statistics do not exist for visitors or ascensions of the stand-alone peak of Carrauntoohil; however, it was recorded that over 125,000 accessed the range in 2017, and 140,000 accessed the range in 2018, the majority of which are related to Carrauntoohil.[ The attraction of the mountain has led to many accidents and fatalities over the years, and by the 50th anniversary of the KMRT in 2017, they recorded having attended more than 40 fatalities in the range, noting that many were "in the immediate Carrauntoohil area". Accidents on the mountain have been attributed to bad weather, late departures combined with darkness on the way down and falling rocks in eroded areas.

Mountain walking
The straightforward route is via the Devil's Ladder, which starts at Cronin's Yard () in the north-east, moves into the Hag's Glen, continues along between Lough Gouragh and Lough Calee, until the Devil's Ladder, a worn path from the glen to the col between Carrauntoohil and Cnoc na Toinne is visible. No special climbing equipment is needed, but caution is advised as the Devil's Ladder has become unstable with overuse; alternatives to the ladder include the Bothar na Gige Zig Zag track (the north-east spur of Cnoc na Toinne ).[ The full route back to Cronin's Yard is and takes 4–5 hours.]
Other popular, but more serious, routes to Carrauntoohil from the Hag's Glen are via the Hag's Tooth Ridge up to Beenkeragh, and then across the Beenkeragh Ridge to Carrauntoohil; or via the Eagle's Nest route to Lough Cummeenoughter, Ireland's highest lake, and up to the summit via Brother O'Shea's Gully or Curved Gully.
Instead of descending via the Devil's Ladder, some climbers use a route known as the Heavenly Gates, which starts above the col of the Devil's Ladder but takes a small stone path that cuts across the east-face of Carrauntoohil, through a narrow gap, known as the Heavenly Gates (see photo), and then heads diagonally down a deep gully to the base of the first level of the Eagle's Nest corrie, where the Mountain Rescue Hut is situated. This route, however, is hazardous, difficult to find as it is not marked, and particularly dangerous in poor visibility; it has been the source of several serious accidents on Carrauntoohil.
A strenuous undertaking is the Coomloughra Horseshoe, which takes 6–8 hours and is described as "one of Ireland's classic ridge walks". It starts from the north-west up the Hydro-Track (), and is usually done clockwise, first climbing Skregmore , and then to Beenkeragh , across the famous Beenkeragh Ridge, at the centre of which is The Bones , and on to the summit of Carrauntoohil itself. The horseshoe is completed by continuing to Caher , Caher West Top , and descending to the starting point. Carrauntoohil is also climbed as part of the full MacGillycuddy's Reeks Ridge Walk, a 12- to 14-hour, traverse of the entire Reeks range.
Rock and winter climbing
Although the Reeks are not particularly known for their advanced rock climbing (e.g. unlike Ailladie in Clare, or Fair Head in Antrim), the east face of Carrauntoohil, looking into the Hag's Glen, and the north-east face, looking into Brothers O'Shea's Gully, have a number of multi-pitch, mixed route, rock climbing routes.[ The most well-known is the Howling Ridge (]climbing grade
Many climbing routes have grades for the technical difficulty, and in some cases for the risks, of the route. The first ascensionist can suggest a grade but it will be amended for the ''consensus view'' of subsequent ascents. While many cou ...
Very Difficult, or V-Diff), which starts at the base of the gap of Heavenly Gates, and takes the arête between Carrauntoohil's east and north-east faces.
These same east and north-east faces are also used for winter climbing, conditions permitting, and seven routes of climbing grade V are marked amongst almost eighty routes in total.
