Benbaun – Galway's highest peak

📍 Connemara National Park, Galway

🏛️ Attraction

Last updated: 28 June 2026

Overview

Benbaun (Irish: Binn Bhán, ‘white mountain’) is the highest point in County Galway at 729 m, and the high centre of the Twelve Bens. The official National Parks figure puts it slightly lower at 725 m, but 729 m is the value most sources and topo maps carry. The name is literal: the pale quartzite that caps the upper slopes catches the light from a long way off. It sits within Connemara National Park, alongside the park’s other Bens – Bencullagh, Benbrack and Muckanaght.

This is not a casual walk. Benbaun is a remote summit with no easy trail to the top, and reaching it means committing to a long day on exposed ridges. If you want the high Connemara experience without that commitment, the easy waymarked trails around the visitor centre near Letterfrack are a different and much gentler proposition.

Naming and status

The name comes straight from the white quartzite of the summit cone. Its prominence of 684 m qualifies Benbaun as a Marilyn and a P600 – classifications hill-walkers use to track Ireland’s most substantial summits – and it is also listed as an Arderin and a Vandeleur-Lynam. As the county top of Galway, it is a target for walkers working through Ireland’s highest peaks.

Geography and landscape

Benbaun sits at the meeting point of the main ridges that tie the Twelve Bens together. It is flanked by glaciated, U-shaped valleys: the Gleninagh Valley to the east, drained by the Gleninagh River and walled by Carrot Ridge, and the Owenglin valley to the south-west. From the summit the view stretches well beyond the park, across blanket bog and heath to the Atlantic coast.

The routes

There is no graded path to the summit. The serious ways up are long ridge circuits that take Benbaun in along with neighbouring peaks:

  • Owenglin Horseshoe – about 20 km, a 10 to 12 hour day, the biggest of them.
  • Gleninagh Horseshoe – about 15 km, 8 to 9 hours.
  • Glencorbet Horseshoe – about 14 km, 6 to 7 hours.

All involve sustained ascent, rough quartzite ground and real navigation. The upper mountain goes featureless in low cloud, so carry the OSi Discovery 37 map, a compass and a reliable GPS, and have the skills to use them.

Rock climbing on Carrot Ridge

On the southern spur of the Gleninagh Valley, Carrot Ridge is a recognised climbing venue. Its quartzite faces hold routes from Diff up to Very Severe, with lines stretching to around 320 m. Conditions change fast, and prior experience on Irish rock is strongly advised.

Wildlife

The lower slopes and surrounding parkland are good for birds: meadow pipits, skylarks and stonechats on the open ground, with kestrels, merlins, sparrowhawks and peregrines hunting over it. The blanket bog and heath hold carnivorous sundews and butterworts, along with orchids and bog cotton through late spring and summer. Connemara ponies graze the park.

Practical information

  • Entry: Free. Benbaun lies within Connemara National Park, which is managed by the National Parks and Wildlife Service and has no admission charge.
  • Parking: Free at the visitor centre near Letterfrack, off the N59. It fills quickly on summer weekends, so arrive early.
  • Public transport: CityLink runs buses from Galway to Connemara via Clifden about three times daily; there is no train.
  • Weather and gear: Connemara weather turns fast. Waterproofs, a warm layer and sturdy boots are needed year-round, and ice and snow are common high up in winter, when crampons and an ice axe may be required.
  • Accessibility: The summit routes are steep, rough and exposed, and are not suitable for wheelchair users. The visitor centre and a short, level nature trail near it are accessible.

Nearby peaks

Benbaun is rarely walked alone. Bencorr lies to the south-east, the second-highest of the Bens, and Benbrack sits across the ridge to the north. The closeness of the peaks is what makes the long horseshoes possible – and what makes a day here a multi-summit undertaking rather than a single climb.

Check the mountain forecast before you commit. The visitor centre carries free trail maps and staff can give current conditions, and on Benbaun that last check is worth more than on almost any other Galway hill.
