Geology
MacGillycuddy's Reeks are composed of sandstone particles of various sizes, which are collectively known as the Old Red Sandstone

period (310–450 million years ago) when Ireland was in a hot equatorial setting. During this 60 million year period, Ireland was the site of a major basin, known as the Munster basin, and the counties of Cork and Kerry were effectively a large alluvial floodplain. Chemical oxidation stained the material with a purple–reddish colour (and green in places from chlorination), still visible today. There are virtually no fossils in Old Red Sandstone. The composition of Old Red Sandstone is variable and contains quartz stones, mudstones
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from ''shale'' by its lack of fissility.Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York ...

Geography
MacGillycuddy's Reeks are variously described as consisting of two main sections, containing all ten of the Reeks that are above 3,000 ft:
The Eastern Reeks meet the Coomloughea Reeks at the col of the '' Devil's Ladder'', a popular ascent route for Carrauntoohil.
MacGillycuddy's Reeks contains the three peaks in Ireland which are over in height, namely: Carrauntoohil

, or "drop" between many of its peaks. Only two of the eleven Reeks over 3,000 ft meet the Marilyn classification of a mountain (a prominence above 150 metres; 500 feet), namely Carrauntoohil and Cnoc na Péiste. The only Reek that meets the P600 classification (a prominence above 600 metres; 2000 feet), is Carrauntoohil itself. The combination of high peaks and low prominence, means the ridges between the peaks are at a sustained height (e.g. why the prominence is so modest), which has contributed to the popularity of ridge walking in the Reeks, particularly, the ''Coomloughra Horseshoe'', and the '' MacGillycuddy's Reeks Ridge Walk'', and the term, "Ireland's highest mountain range".
Ownership
The entire range is held in private ownership, both in individually owned freehold parcels in the lower reaches and in commonly owned, open upland zones ('commonage'). 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, the MacGillycuddy's Reeks are not part of a national park or a trust structure.[
The private ownership has led to issues around the upkeep of popular paths in the Reeks, most particularly the erosion of the ''Devil's Ladder'' path, which is used to summit Carrauntoohil; and various car-parks and bridges used by climbers.] The 2013 MAP report noted the importance of safety in light of the increasing climbers and walkers to the Reeks. The MAP report stated that Kerry Mountain Rescue ("KMR") logged 17 fatalities on the Reeks between 1966 and 2000, or about one every second year, but since 2000, KMR had been logging approximately 2 fatalities per annum.[

Naming
The full name of the range in Irish is ''Cruacha Dubha Mhic Giolla Mo Chuda'', meaning "the black stacks of McGillycuddy". This is commonly shortened to ''Na Cruacha Dubha''. The name is translated into English as "MacGillycuddy's Reeks", where ''reek'' is a Hiberno-English

The MacGillycuddys () were a sept, or branch, of the O'Sullivan Moore clan. The MacGillycuddy is recorded as being one of a smaller number of Gaelic chieftains whose lands were returned post the Cromwellian confiscations, which explains why the name survives to this day. The MacGillycuddy family tomb is at Kilgobnet, County Kerry, between the mountains and Killorglin
Killorglin () is a town in County Kerry, Ireland. As of the 2022 census, the town's population was 2,163. Killorglin is on the Ring of Kerry tourist route, and annual events include the August Puck Fair festival, which starts with the crownin ...

Recreation
Visitors
Jim Ryan's 2006 book on the Reeks, ''Carrauntoohil and MacGillycuddy's Reeks: A Walking Guide to Ireland's Highest Mountains'', stated that there were 25,000 annual visitors to the Reeks. The 2013 MAP report quoted Ryan's figures, which were cited in the MAP's ''Terms of Reference'', but stated that: "The Reeks are accessed by at least 25,000 recreational users per annum. It is highly likely that the numbers are a factor of 4 times higher based on observation of the year-round level of usage – but data is required to ascertain the visitor numbers." It was estimated that 125,000 visitors entered the range in 2017 from footfall at three main access points, and that 140,000 entered in 2018 by recording footfall at four main access points. The Reeks are a popular subject for artists and photographers, with souvenir prints offered for sale among "Views of Ireland."
Hill walking
The most common reason for visiting the Reeks is to climb Ireland's highest mountain, Carrauntoohil. The popular route starts from Cronin's Yard () and enters the Hag's Glen to climb the ''Devil's Ladder'' (the col between Carrauntoohil

and Cnoc na Toinne), from which the summit is accessed. A more challenging route is via the '' Hag's Tooth Ridge'' which circles the ''Eagle's Nest'', and takes in Beenkeragh, and the ''Beenkeragh Ridge''.
MacGillycuddy's Reeks is particularly regarded for the quality of its ridge walking routes, with the 6–8 hour ''Coomloughra Horseshoe'', that circles Lough Coomloughra, considered "one of Ireland's classic ridge walks", which takes in all three of Ireland's peaks, namely, Carrauntoohil, Beenkeragh, and Caher (East Top and West Top), as well as the famous '' Beenkeragh Ridge''.
The most challenging route is the full ''MacGillycuddy's Reeks Ridge Walk'', a 12- to 14-hour, traverse of the entire range. The route normally starts at the eastern end from ''Kate Kearney's Cottage'' in the Gap of Dunloe. The route takes in Stickeen Mountain () and Cnoc an Bhráca () before reaching the ridge proper at Cruach Mhór

An alternative variation is to continue from Beenkeragh on the northern side of the ''Coomloughra Horseshoe'' to the peaks or Skregmore () and Cnoc Íochtair () before descending to the ''Hydro-Track'' car park.
Rock and winter climbing
MacGillycuddy's Reeks are not especially known for their rock-climbing routes, unlike Ailladie in Clare or Fair Head in Antrim. The rock climbing grade Very Difficult (V-Diff), '' Howling Ridge'' up the central arete between the east and north-east faces of Carrauntoohil is notable. The north-east face of Carrauntoohil (e.g. the '' Eagle's Nest'' area), is better known for its winter climbing, conditions permitting, offering 80 routes with 7 up to winter Grade V.
