Overview
Mount Brandon (Cnoc Bréanainn) is the highest mountain in Ireland outside the MacGillycuddy’s Reeks, eighth on the country’s Arderin list of peaks at 952m. It runs along the northern spine of the Dingle Peninsula in County Kerry, and its two faces could belong to different mountains: a broad grassy western slope, and an eastern flank torn into steep corries and cliffs by glaciers. The summit is a windswept plateau where a large iron cross and the ruins of a stone oratory mark the end of one of Ireland’s oldest pilgrim routes. On a clear day the top gives you the Blasket Islands, the sweep of Dingle Bay and, if you’re lucky, the distant Aran Islands.
Which route to take
Three approaches, and the choice matters more than the summit does.
- Cosán na Naomh (the Saints’ Route): The easiest and quickest way up, starting from Baile Breac on the west. Grassy underfoot before it turns rocky, roughly 4–5 hours return. This is the one to pick if you want the summit without the exposure.
- Faha Grotto Route: From Cloghane on the east side, about 10km and 6–7 hours, climbing through a glaciated valley past a chain of paternoster lakes – the Coumaknock Loughs, Lough Nalacken, Lough Cruttia. The upper section needs careful footing and some light scrambling. It’s harder work than the Saints’ Route, and it’s the one most people remember: the lakes and the corrie walls do the heavy lifting.
- Brandon Ridge Walk: The full traverse of seven peaks, 6–9 hours, for confident navigators only. A classic Irish ridgewalk, and a serious day out.
If you only have one shot at it and reasonable legs, do the Faha Grotto route for the scenery and start early.
Saint Brendan and the pilgrim path
The mountain takes its name from Saint Brendan the Navigator (c. 484 AD), who by legend fasted here before setting out on his Atlantic voyage. The Cosán na Naomh, the Saints’ Road, has carried pilgrims for centuries, past fourteen Stations of the Cross and older stone markers, and the path is thought to predate Christianity as a route walked at Lughnasadh, the harvest festival. At the summit, the small shelter of Séipéilín Bréanainn sits beside the iron cross – a quiet spot to stop and get your breath after the last pull.
Geology and landscape
Brandon is built from Old Red Sandstone, the purple-reddish Devonian rock that gives the eastern corries their colour. Those corries – scooped out during the last ice age – hold the string of glacial lakes you pass on the Faha side, dammed one below the next like beads on a thread. The contrast with the smooth grassland to the west is the whole character of the mountain, and the reason the two routes feel so different.
Wartime wrecks
The high ridges and fast-changing weather made this a dangerous place to fly in the war years. Several aircraft came down on the slopes between 1940 and 1943, including a German Focke-Wulf Condor and a BOAC Sunderland flying boat, and fragments still lie scattered among the rocks on the Faha side. A memorial bench near the summit remembers the crews, and there’s a plaque down in Cloghane at O’Connor’s Bar.
Practical information
- Parking: Free car parks at Baile Breac (west) and near the Faha Grotto (east). The Faha lot only holds about eight cars, so on fine summer days and weekends it fills early – get there before mid-morning or you’ll be parking on the road.
- Navigation: Trails are waymarked with white poles and stone crosses, but carry the OSI Discovery Series 70 map and a compass. Mobile reception is unreliable on the ridges, so don’t count on your phone.
- Best time to go: May to September gives the most stable weather. Start early – cloud builds up over the summit through the afternoon and will rob you of the view you came for.
- Safety: The weather turns fast up here. Pack waterproofs, proper boots, food and water, and tell someone your route and expected return. Dogs are welcome on the trails but keep them under control.
- Guided walks: Operators such as Kerry Climbing run guided ascents, usually meeting at the Mount Brandon Hostel in Cloghane, taking in route-finding and the history along the way. Reckon on 5–6 hours.
- Afterwards: There are no facilities on the mountain. Cloghane and the Gaeltacht village of Brandon, both at the foot of the slopes, have pubs, food and traditional music – Cloghane’s O’Connor’s Bar is the natural place to end up.
Nearby
- Brandon Bay – sheltered water for kayaking and long strand walks.
- Conor Pass – a dramatic mountain road with cliff-edge views and its own glacial lakes.
- Gallarus Oratory – an early medieval stone oratory, remarkably intact, a short drive south.
