Overview:
Distance: approx. 12km round trip
Elevation gain: 746m
Format: Out and back
Time: 4+ hours
Start / End / Parking:
I parked on the Lettershanbally Trail Head (google maps link) on the R344 outside of the Glencorbet valley. Thereβs space for up to 10 cars, if some strategic planning is done.
If youβre looking to approach from the Glencorbet valley, this is the recommended parking spot as of June 2026. The locals of Kylemore ask hikers not to park further into the valley due to congestion and blocked access occurring.Trail difficulty: Moderate - Difficult
The first half of this route follows a dirt track up the valley, and the second half is wild, open mountainside. This becomes a βdifficultβ rating for me because of the prolonged rocky, steep sections, and mountain terrain without clear paths. An ability to deal with mountain hazards, steep ground and scree is essential.
Read about trail grading in Ireland here.Trail quality: 5/5
I donβt know if having a βtrail qualityβ section for this mountain is appropriate, as while the lower half of the route uses a wide track in through the valley (there is a river to ford), the upper half of this route is not a trail and contains open mountainside and loose rock. This requires experience on moving on loose rock, as well as confident navigation skills for if there is cloud cover or bad weather blows in.Views: 5/5
I love Galway and all the mountains you find here. I love the rugged nature of the Bens, and the wild, windy landscape is inspiring. You wonβt always have views in these mountains (the weather changes too fast for it ever to remain one way for long), but the moments you have are breathtaking.Buggy/Wheelchair friendly: No
Dogs allowed: No - this route features farmland and possible livestock.
When did I walk this route: June 2026

Itβs a beautifully sunny Friday afternoon as I drive across Mayo and down through Killary Fjord to the start of my hike. This is truly one of the best parts of the Irish summer - if you finish work early enough, you can escape and fit a whole day of hiking into the long evenings.
I pull into the small car park at the entrance to Lettershanbally Forest and quickly pack my bag. Itβs 4pm as I set off up the road. The first 10 minutes or so is along the R344, which is quite a busy road. Keeping eyes and ears open, I only have to step in a handful of times before I turn off onto the small boreen that leads you into the Glencorbet valley. Another 500m down the boreen, and as the lane turns right, I turn left onto the wide rocky track.
For the next approx. 2km I follow this fairly straight track along the valley floor. I settle into an easy pace as I meander along the riverside. However, as I round a slight bend, Iβm pulled up short. Itβs time to cross the river, but there is no bridge. I look at the EastWest map of the area, and sure enough, a ford is marked here (but not marked on the OSI). I could walk back along the river and see if thereβs a section with suitable-looking stepping stones, but I hadnβt really noticed any on the way in, so I peel off my socks and wade in. The cold water is almost pleasant in the warm sun. The water goes as high as my upper calf (although itβs worth remembering that I am quite short). Drying my legs and feet with the ends of my trousers, I continue on along the old road.
At the end of this lane, I found myself in a small yard. The way that felt like the way the farmer intended walkers to take, was to actually head downhill, and use the gate towards the river. This is the only gate that wasnβt locked or similar. Taking this gate means you can loop down towards the river and then around the fenced sheep pens. Always leave gates as you find them and/or follow the signs on them. Iβll always be very grateful to the landowners who give access to the hills.
From here, it is open mountainside to the summit. The first half is still grassy, and very steep. Looking at the maps, I chose the streams I wanted to stay between as I climbed up to the col between Benbaun and the 457m spot height to the NE. There are plenty of sheep trails and soil creep to give the illusion of a βtrueβ trail.
The second half of this climb is made up of the loose rock that the bens are famous for. Itβs about 1km and 280m of climbing left to the summit, but I try and forget about either as I slowly zig-zagged my way through the steep scree. Just as I reach the broken trig point, clouds start to stream in from the sea. The speed that they pour over the shoulder is breath-taking, and I watch them fly past as I eat my snacks. My brother rings me, and I shelter in the piled up rocks and enjoy the novelty of both feeling completely disconnected from the rest of the world, while talking to someone many hours and hundreds of kilometres away.
As I descend, a heavier bank of clouds settle in above me. I quickly pick my way back down, revelling in having the mountain completely to myself. As I begin to reach the col once more, a stunning rainbow lights up the Gleninagh River in the valley south of mine. I take more photos than makes any sense, in love with the colours and evening light.
The re-tracing of my steps is as exact as it can be without a trail underfoot, and soon enough the ground is levelling out once more. I meet a frog or two in the wet grass. I take off my wet shoes and socks for one more river crossing - at this point there was plenty of bog in the shoes that taking them off probably wasnβt making much of a difference. In the summer months Iβm happy enough to accept the wet feet if it means I can wear the trail shoes that Iβve come to love (as always, assess your own feet and footwear for what you need yourself).
Itβs as Iβm almost back to the boreen, the main road in sight up ahead, that the heavens open and decide to lash on me for the remainder of my walk back to the van. It almost felt like a karmic re-balancing, taking payment for the beautiful weather Iβd enjoyed all evening on the mountain itself.
Itβs approaching 10pm as I slide open the door and climb in out of the wet - hanging layers haphazardly to hopefully dry out before my weekend of shadowing mountain skills courses. Iβm content as I eat my lunchbox dinner and plan my nightβs sleep.
Itβs hopefully obvious from the text above, but this mountain is not an easy stroll. Itβs one of the wilder places you can visit in Ireland, and deserves respect. If youβre someone completing the County High Points List, this mountain is firmly in the βhardβ end of the list, along with the likes of Carrauntoohil and Mweelrea. If youβre new to the hills, Iβd strongly recommend finding a local mountain leader to take you (send me an email if you need a recommendation).

I donβt have a specific write up for this walk, but itβs a lovely short hike that takes in a section of the Western Way as you climb up to a pass in the Maumturks (one of Galwayβs mountain ranges). Itβs approx. 4km total out and back.
