Overview
- Ben Challum - Munro - Callum’s Hill - 1,025m elevation
Elevation Profile
Ben Challum is a big, imposing mountain that sits just south of Tyndrum. You can see it from the A82 and from the village itself — it dominates the skyline and always looks like a proper beast of a hill. At 1,025m, it breaks the 1,000m mark and you certainly feel every metre of it on the way up.
This was Munro number 34 for us and it proved to be a tough but rewarding day out. The weather was mixed — as it so often is in the Highlands — but we managed to grab some decent views between the clouds.
Route Overview
Getting There and Parking
We parked up at the small layby on the A82 just south of Tyndrum near Kirkton Farm. There’s room for maybe 10-15 cars here and it’s free. The start of the route is well signposted from the road.
Stage 1 - The Walk In
From the car park, you cross the bridge over the River Fillan and follow the path through some farmland. The initial section is flat and boggy in places — classic Highland walking. You’ll want gaiters or at least waterproof boots for this bit as the path has a tendency to disappear into the bog.
After about 1km, you’ll start to see the bulk of Ben Challum rising above you and the path begins to steepen. There’s a fence line that you follow for a good while which helps with navigation in poor visibility.
Stage 2 - The Ascent
The climb up Ben Challum is relentless. There’s no real respite once you start gaining height — it’s just a steady, steep slog upwards. The path follows the south ridge and is reasonably well defined, though it does become less obvious in places as you get higher.
Around the halfway point, you reach a false summit which can be a bit demoralising when you realise there’s still a fair bit of climbing to go. The terrain becomes rockier and more exposed as you push on towards the true summit.
The final section across the summit plateau is relatively flat but can be featureless in clag. On our day, the clouds were dancing in and out, giving us tantalising glimpses of the surrounding mountains before whipping them away again.
Stage 3 - Summit and Descent
The summit cairn sits on a small rocky outcrop and offers brilliant views on a clear day — you can see across to Ben More and Stob Binnein, the Crianlarich hills, and further north towards the Bridge of Orchy mountains.
We had our usual jam sandwiches at the top, huddled behind the cairn to shelter from the wind, before retracing our steps back down the same way we came up.
The descent is straightforward but hard on the knees given the steepness. Take your time on the rockier sections and enjoy the views opening up as you drop back down towards the glen.
Conclusion
Ben Challum is a proper mountain that demands respect. The 987m of ascent over a 12.79km route means it’s no walk in the park, but the reward is a summit that feels genuinely remote and wild. The views on a clear day are fantastic and even in the clag, there’s a real sense of being up in the mountains.
If you’re based in Tyndrum or passing through on the way further north, this is a great one to tick off. Just make sure your legs are up for it — the relentless gradient is the real challenge here.
