Binn idir an dá Log (Irish: Binn idir an dá Log, meaning peak between the hollows) at 702 metres (2,303 ft), is the 87th–highest peak in Ireland on the Arderin scale, and the 108th–highest peak on the Vandeleur-Lynam scale. Binn idir an dá Log is situated at the centre of the long north-west to south-east cental spine of the Maumturks mountain range in the Connemara National Park in Galway, Ireland. Binn idir an dá Log is the tallest mountain in the range.

Naming

Binn idir an dá Log derives its name from the two glacial corries that bound each end of its high rocky summit ridge (the north-western corrie is a lake).

Binn idir an dá Log is sometimes incorrectly named as "Barrslievenaroy" (or "Baurslievenaroy") (Irish: Barrshliabh na Ráthadh; the mountain fort), which is a small townland on the northern slopes of the mountain that is marked in some Ordnance Survey Ireland maps. The Placenames Database of Ireland records an anglicised version as "Benadolug", however, this does not appear in other noted Irish mountain placename reference guides.

Geography

Binn idir an dá Log lies at the centre of the long north-west to south-east central spine of the Maumturks range in the Connemara National Park. The mountain has a high winding rocky summit ridge, littered in quartzite rocks and gravel, that includes the subsidiary peak of Binn idir an dá Log SE Top at 659 metres (2,162 ft). To the southeast of the summit ridge is a large corrie (and the townland of Barrslievenaroy below), and then the 4th highest Maumturk of Binn Chaonaigh at 633 metres (2,077 ft).

To the northwest of the summit ridge is an even larger corrie lake (at L 879536), with steep cliffs on its backwall, which then rises up again to the summit of Knocknahillion at 607 metres (1,991 ft). The col between Binn idir an dá Log and Knocknahillion is the pass of Maumahoge (Irish: Mhám Ochóige, and the corrie lake is called Lough Maumahoge (Irish: Loch Mhám Ochóige).

Binn idir an dá Log's prominence of 644 metres (2,113 ft) qualifies it as a P600, and a Marilyn, and it also ranks it as the 52nd-highest mountain in Ireland on the MountainViews Online Database, 100 Highest Irish Mountains, where the minimum prominence threshold is 100 metres.

Hill walking

The easiest way summit Binn idir an dá Log is a 6-kilometre 3-hour route via the pass of Maumahoge; however, because of its positioning on the high rocky central spine of the central Maumturk range, it is also summited in a longer 13-kilometre 5-6 hour loop-route starting at the col of Maumeen Irish: Máméan, in the south, climbing Binn Chaonaigh and then onto the top of Binn idir an dá Log, before descending via Maumahoge, and walking back.

Binn idir an dá Log is also climbed as part of the Maamturks Challenge, a 25-kilometre 10–12 hour walk over the full Maumturks range (from Maam Cross to Leenaun), which is considered one of the "great classic ridge-walks of Ireland", but of "extreme grade" due to the circa 7,600 feet of total ascent.

Since 1975, the University College Galway Mountaineering Club, has run the annual "Maamturks Challenge Walk" (MCW), and man two checkpoints on Binn idir an dá Log; one at the summit (the summit marks 54% of MCW climbing completed), and another at Lough Maumahoge (the Lough marks 63% of MCW climbing, and 51% of MCW distance, completed), which has a 2pm cut-off time for participants.

Rock climbing

While the Maumturks range is not particularly known for rock climbing routes (unlike Bencorr and its Carrot Ridge spur, across the Inagh Valley), some have been developed at a crag just below and west of Lough Maumahoge (L876 532), with routes of 90 to 190 metres at climbing grades of S to HVS.
