The Twelve Bens or Twelve Pins, also called the Benna Beola [2] (Irish : Na Beanna Beola, meaning 'the peaks of Beola'), [lower-alpha 1] is a mountain range of mostly sharp-peaked quartzite summits and ridges in the Connemara National Park [lower-alpha 2] in County Galway, in the west of Ireland. [4] The widest definition of the range includes the Garraun Complex to the north as well as several isolated peaks to the west, and is designated a 16,163-hectare (39,940-acre) Special Area of Conservation. [5]
The highest point is Benbaun at 729 metres (2,392 ft). [6] The range is a popular location for hill-walking activities with the 16–kilometre 8–9 hour Glencoaghan Horseshoe, considered one of the best ridge-walks in Ireland. [7] [6] Topographically, the range is partnered with the Maumturks range to the east of the Inagh valley (a Western Way route); [6] and both share a common geology being largely composed of metamorphic marine rocks, being predominantly resistant quartzite but with deposits of schists in the valleys (known as Connemara Dalradian rocks). [8]
"Ben" is an anglicized form of the Irish word binn, meaning "peak". [3] According to Irish academic Paul Tempan, [lower-alpha 3] "An odd thing about the Twelve Bens of Connemara is that nobody seems to know exactly which are the twelve peaks in question", and noting that there are almost 20 peaks with "Ben" or "Binn" in their name. [3] [9] Tempan notes that term "twelve peaks" can be at least dated to the Irish historian Ruaidhrí Ó Flaithbheartaigh, whose writings in 1684 said: "On the north-west of Ballynahinsy [Ballynahinch], are the twelve high mountaines of Bennabeola, called by marriners the twelve stakes [stacks], being the first land they discover as they come from the maine [sea]", but he did not list them. [3]
The most common list of the twelve peaks in question are the peaks with an elevation above 500 metres in the core range, and that are not considered subsidiary peaks (e.g. they have a non-trivial prominence, and have been traditionally noted as peaks on historic maps, per § List of peaks below). [6]
Tempan notes the issue of "twelve" does not arise in the Irish language name as they are simply labelled Na Beanna Beola, which translates as "the peaks of Beola". [3] Beola was a leader of the Fir Bolg, and a giant; his name appears in that of the Connemara village Toombeola. [3]
The Twelve Bens range is a core massif of 22 peaks above 100 metres (330 ft) in elevation, centred around the highest peak in the range, Benbaun 729 metres (2,392 ft). To the north of this core massif lies the separate subsidiary massif of the Garraun Complex with 9 peaks around Garraun 598 metres (1,962 ft). To the west of the core massif lies 7 other isolated or subsidiary "outlier" peaks, thus giving a total of 38 Bens with an elevation above 100 metres. [6] [7]
While the Bens are not as high as those of the ranges in County Kerry (e.g. MacGillycuddy's Reeks and the Mountains of the Dingle Peninsula), their rocky peaks and ridges contrast with the surrounding sea-level landscape (unlike Kerry, there are no mountain-passes in Connemara), and give the range an imposing feel. [6] [7]
The range is bounded by the Inagh Valley and the R344 road to the east, while the N59 road (or the "Clifden Road"), circles and bounds the core massif (and most of the outliers), from the southerly, westerly and northerly directions. The Garraun Complex lies to the north of the N59 road at Kylemore Lough. [6] [7]
The 22 peaks in the core massif of the Twelve Bens range naturally split into three sections: [11]
The core massif is also known for its deep glaciated U-shaped valleys, around which groups of Bens lie in a "horseshoe formation": [11]
The core massif of the Twelve Bens range is largely composed of metamorphic marine rocks, being predominantly resistant quartzite but with deposits of schists in the valleys (known as "Connemara Dalradian" rocks). [8] [5] [17]
These rocks derive from sediments that were deposited in a warm shelf sea some 700 to 550 million years ago (e.g. Precambrian-Cambrian). [17] Movements in the Earth's crust, and the closure of the Iapetus Ocean, transformed these sediments into crystalline schists that lie underneath the base of the mountain range, which local erosion and uplift then brought to the surface. [8] [17] The summits of the core massif (and some outliers) are made of weather-resistant quartzite, while the sides of the peaks are composed of schists and grey marbles. [17]
In contrast, the mountains to the north of the core Twelve Bens massif, the Garraun Complex, have a different type of geology, that is composed of gneiss and different forms of sandstones and mudstones. [5]
Scattered throughout the range are parts of gabbro (Doughruagh and Currywongaun), mica schist (Muckanaght), and outcrops of marble (south of Kylemore Lough). [5]
The final Ice Age, circa 10,000 years ago, also sculpted the landscape leaving behind deposits of sand and gravel; there are widespread boulder-clay and erratic boulders across the range. [17]
The entire Twelve Bens range (including the Garraun Complex) is a Special Area of Conservation (SAC) (Site Code:002031), as selected for a range of habitats and species listed under the Annex I / II of the E.U. Habitats Directive. [5] The items of note on the SAC habitats list includes: Oligotrophic Waters, Alpine Heaths, Active Blanket Bogs, remnants of Oak Woodland, Rhynchosporion Vegetation, and Siliceous Scree and Rocky Slopes; while the species list includes: Freshwater Pearl Mussel, Atlantic Salmon, Otter, and Slender Naiad. [5] In addition, the 16,163-hectare site includes a some of the rarer Red Data Book species of plant. [5] The SAC directive on the range describes it as "One of the largest and most varied sites of conservation interest in Ireland". [5]
The range is popular with hill walkers, fell runners, and rock climbers, [18]
The Irish Times outdoors correspondent, John G. Dwyer, said of the Twelve Bens, "These are true kickass mountains, with criminally stunning views [..]". [19]
The 16-kilometre (9.9 mi) 8–9 hour Glencoaghan Horseshoe [lower-alpha 4] is noted as providing some of the "most exhilarating mountaineering in Ireland", [23] and is called "a true classic" by guidebook authors. [7] [6] [12] Other similar distanced "horseshoe" loop walks are the 19–kilometre 10–12 hour Owenglin Horseshoe, [13] the 15–kilometre 8–9 hour Gleninagh Horseshoe, [14] and the 14–kilometre 6–7 hour Glencorbet Horseshoe. [16] [15]
An even more serious undertaking is the 28-kilometre (17 mi) "Twelve Bens Challenge", climbing all 12 Bens in a single 24-hour day. [lower-alpha 5]
The Twelve Bens have a number of rock climbing locations, the most notable of which is in the Gleann Eighneach valley at the eastern spur of Benncorr (from Binn an tSaighdiúra to Bencorrbeg; also called "Carrot Ridge"). The climbs vary from Diff (D) to Very Severe (VS) and range from 150 metres to 320 metres in length, with notable routes being Carrot Ridge (275m D), and Seventh Heaven (330m HS). [18]
In addition, the large easterly corrie between the summits of Derryclare and the summit of Bencorr, known as Irish : Log an Choire Mhóir (meaning "wood of the big corrie"), also contains several large 200 metre multi-pitch graded rock climbs at grades of Diff (D) to Very Diff (VD), the most notable of which is "The Knave" (VD, 225 m); and the smaller corrie between the summit of Bencorr and the summit of Bencorr North Top, known as Log an Choire Bhig, ("wood of the small corrie"), has a number of shorter but harder climbs including "Corner Climb" (VS 4c, 30 m). [25]
The following is a download from the MountainViews Online Database , who list 38 identifiable peaks in the wider Twelve Bens range (i.e. core massif, Garraun complex, and various outliers to the west), with an elevation, or height, above 100 metres (328 ft)
The list below highlights the 12 Bens most associated with being the Twelve Bens from Ó Flaithbheartaigh's original record. [6] Of the standalone "Bens" (e.g. not listed as a "Top" of a parent Ben) that are over 500 metres (1,640 ft) in height but are not listed in this 12, Binn an tSaighdiúra has a prominence of only 8 metres and would not qualify as an independent mountain on any recognised scale (the lowest prominence is 15 metres for the Vandeleur-Lynam classification); Maumonght does have a prominence exceeding 50 metres, and even has a subsidiary peak (Maumonght SW Top), however, Maumonght rarely appears on historic maps of the range and is not considered a "Ben"; [3] Bencorrbeag also has a non-trivial prominence of 42 metres, however, it is considered unlikely given its positioning that it could have been distinguished by mariners from the sea (Ó Flaithbheartaigh's original premise).

With a height of 729 metres (2,392 ft), it is the 72nd highest peak in Ireland on the Arderin scale, and the 88th highest peak on the Vandeleur-Lynam scale. Benbaun is situated at the centre of the core massif of the Twelve Bens mountain range in the Connemara National Park and is the tallest mountain of the Twelve Bens range, and the county top for Galway.
Bencorr at 711 metres (2,333 ft), is the 82nd–highest peak in Ireland on the Arderin scale, and the 102nd–highest peak on the Vandeleur-Lynam scale. Bencorr is situated near the centre of the core massif of the Twelve Bens mountain range in the Connemara National Park in County Galway, Ireland. It is the second-tallest mountain of the Twelve Bens range, after Benbaun 729 metres (2,392 ft); it lies close to Benbaun, separated only by the third-highest mountain in the range of Bencollaghduff 696 metres (2,283 ft), and the col of Maumina.
The Maumturks or Maamturks is a mountain range in Connemara, County Galway, in the west of Ireland. It is a long, broadly-straight range, consisting of weathered quartzite peaks in its central section. The Maumturks lie east of the Twelve Bens, on the other side of Lough Inagh and the Inagh Valley.
Letterbreckaun is one of the Maumturk Mountains of Connemara in County Galway, Ireland. At 677 metres (2,221 ft), it is the second-tallest of the Maumturks, the 129th–highest peak in Ireland on the Arderin list, and 159th–highest on the Vandeleur-Lynam list. Letterbreckaun is in the middle sector of the long north-west to south-east spine of the Maumturks.
Garraun at 598 metres (1,962 ft), is the 224th–highest peak in Ireland on the Arderin scale, however, while it is just short of the elevation threshold of 600-metres for other classifications, it does have the prominence to be a Marilyn. Garraun lies on an isolated massif near the mouth of Killary Harbour at the far north sector of the Twelve Bens/Garraun Complex Special Area of Conservation in the Connemara National Park in County Galway. The southern slopes are a scenic backdrop to Kylemore Abbey and Kylemore Lough.
Diamond Hill or Bengooria is an isolated peak overlooking the village of Letterfrack, in the northwest corner of the Twelve Bens in Connemara National Park in County Galway, Ireland. At only 442 metres (1,450 ft), it does not rank as an Arderin, or a Vandeleur-Lynam; however, it has the prominence to rank as a Marilyn.
Bencollaghduff at 696 metres (2,283 ft), is the 93rd–highest peak in Ireland on the Arderin scale, and the 115th–highest peak on the Vandeleur-Lynam scale. Bencollaghduff is situated near the centre of the core massif of the Twelve Bens mountain range in the Connemara National Park in County Galway, Ireland. It is the 3rd tallest mountain of the Twelve Bens range, after Benbaun 729 metres (2,392 ft), to which it is connected by the northern col of Maumina; and after Bencorr 711 metres (2,333 ft), to which it is connected by a high southeast rocky ridge.
Lough Inagh is a freshwater lake in the Inagh Valley, in Connemara, County Galway, in the west of Ireland.
Derryclare Lough is a freshwater lake at the entrance of the Inagh Valley, in Connemara, County Galway, in the west of Ireland.
Benbreen at 691 metres (2,267 ft), is the 100th–highest peak in Ireland on the Arderin scale, and the 122nd–highest peak on the Vandeleur-Lynam scale.

Benbreen is the 4th-tallest mountain of the Twelve Bens range, after Benbaun 729 metres (2,392 ft), Bencorr 711 metres (2,333 ft), and Bencollaghduff 696 metres (2,283 ft). Benbreen's profile is of a "high narrow rocky ridge with several summits", than a typical "peaked mountain".
Bengower at 664 metres (2,178 ft), is the 135th–highest peak in Ireland on the Arderin scale, and the 166th–highest peak on the Vandeleur-Lynam scale. Bengower is in the southern end of the Twelve Bens mountain range in the Connemara National Park in County Galway, Ireland, and is the 6th-tallest of the core Twelve Bens.
Derryclare or Derryclare Mountain is a mountain at the southern edge of Twelve Bens range in Connemara National Park in County Galway, Ireland. At 677 metres (2,221 ft), it is the 119th–highest peak in Ireland on the Arderin list, and the 145th–highest peak on the Vandeleur-Lynam list. It is the 5th tallest of the core Twelve Bens. The Derryclare Lough on its southern slopes is a scenic location in Connemara, while Derryclare Wood, on its eastern slopes, contains a Statutory Nature Reserve (SRN).
Knocknahillion is one of the Maumturk Mountains of Connemara in County Galway, Ireland. At 607 metres (1,991 ft), it is the 210th–highest peak in Ireland on the Arderin list, and 256th–highest on the Vandeleur-Lynam list. Knocknahillion is in the middle sector of the long north-west to the south-east spine of the Maumturks. The summit is offset to the west of the rocky central ridge of the Maumturks, and its western-facing slopes have a distinctive "diagonal" rock stratification when viewed from the Inagh Valley.
Benbrack at 582 metres (1,909 ft), is the 251st–highest peak in Ireland on the Arderin scale; while it does not have the elevation to be a Vandeleur-Lynam, it has the prominence to rank as a Marilyn. Benbrack is situated on its own small massif to the north of the core Twelve Bens mountain range in the Connemara National Park in County Galway, Ireland. It is the 10th-tallest of the core Twelve Bens, and is linked by a deep col to Muckanaght, which is itself attached by a high ridge to the tallest mountain of the Twelve Bens range, Benbaun at 729 metres (2,392 ft).
Benlettery at 557 metres (1,827 ft), is the 259th–highest peak in Ireland on the Arderin scale. Benlettery is in the southernmost peak of the Twelve Bens mountain range in the Connemara National Park in County Galway, Ireland, and is the 11th-tallest of the core Twelve Bens. The Ben Lettery An Oige youth hostel is on the southern slopes of Benlettery, off the N59 road to Clifden.
Benglenisky at 516 metres (1,693 ft), is the 368th–highest peak in Ireland on the Arderin scale. Benglenisky is the second most southern peak, after neighbouring Benlettery, of the Twelve Bens mountain range in the Connemara National Park in County Galway, Ireland, and is the lowest of the core Twelve Bens.
Mullach Glas is one of the Maumturk Mountains of Connemara in County Galway, Ireland. At 622 metres (2,041 ft), it is the fifth-highest of the Maumturks, the 197th–highest peak in Ireland on the Arderin list, and 238th–highest on the Vandeleur-Lynam list. Mullach Glas is on a massif that includes Binn Mhór and Corcogemore ; this massif is at the far southeastern sector of the long north-west to south-east spine of the Maumturks.
Leenaun Hill at 618 metres (2,028 ft), is the 201st–highest peak in Ireland on the Arderin scale, and the 243rd–highest peak on the Vandeleur-Lynam scale. Leenaun Hill lies on a massif that overlooks Leenaun village and Killary Harbour, and which is at the far northeastern sector of the Maumturks mountain range in the Connemara National Park in County Galway, Ireland; this massif is connected to the main range via the "Col of Despondency". Leenaun Hill is the 6th-highest mountain in the Maumturks, and its grassy massif, constructed from sandstone and siltstone, contrasts with the rocky ridges and summits constructed from quartzites, grits, and graphitic, of the middle and southern sectors of the range.
Lissoughter or Lissoughter Hill is a prominent hill between the Twelve Bens and Maumturks mountain ranges, at the southern entrance to the Inagh Valley, in the Connemara National Park of County Galway, Ireland. With a height of 401 metres (1,316 ft), it does not qualify to be an Arderin or a Vandeleur-Lynam, however, its prominence of 336 metres (1,102 ft) ranks it as a Marilyn.
Ben Lugmore at 803 metres (2,635 ft) is the 29th-highest peak in Ireland on the Arderin scale, and the 37th-highest peak on the Vandeleur-Lynam scale. It is in a horseshoe-shaped massif that includes the slightly higher peak of Mweelrea at 814 metres (2,671 ft), the highest mountain in the Irish province of Connacht. The massif is between Killary Harbour and Doo Lough, in County Mayo.

Route 11: Glencorbet Horseshoe
ROUTE 33: The Glencorbet Horseshoe. A true classic
The finest rock formations in the Twelve Bens are found in the south wall of Gleann Eidheanach (Glen Inagh), running from Binn an Choire Bhig to Mám na bFhonsaí, east of Binn Dubh (L808530).
Even if you had to crawl across bogs to get to them, it would be worth it as the nine [should be six] peaks which form the Glencoaghan Horseshoe provide some of the most exhilarating mountaineering on this island.
The route begins at the Inagh Valley Inn and ends at the Bard's Den in Letterfrack. The total distance covered is approximately 28km and the total height gain for the route is approximately 2530m (8300ft). On average it takes 12–14 hours to complete and should only be attempted by competent hill-walkers.
