Beinn Challuim [Ben Challum]

Beinn Challuim [Ben Challum]

Ben Challum is a 1024.9 m Munro above Strathfillan near Tyndrum and Crianlarich. The main summit is beyond a separate 998.3 m South Top, which can hide it on the southern approach.

Route from Kirkton Farm

The complete out-and-back from the A82 layby near NN355281 is 11.5 km with 910 m of ascent, taking around 5–7 hours. The layby is on the west side of the road, just north of the Kirkton Farm turn. Cross the road carefully and follow the farm lane, then a short section of the West Highland Way past the chapel and burial grounds. Fork right onto the path to the railway footbridge. Use this bridge rather than historical level-crossing directions.

Above the railway, follow the faint path and fence line across very boggy slopes to the South Top. From there, turn briefly west to cross the cleft before following the ridge north. A short descent and further climb reach the main summit. Retrace the ridge to the South Top and return by the whole outward route to the layby. The distance and time cover this complete return.

This is a strenuous mountain walk with significant ascent, wet ground and navigation demands. A faint path is no guarantee of easy route-finding. Take particular care at the South Top in mist, and do not head blindly north or east towards steep ground. Carry mountain clothing and independent navigation; snow or ice requires appropriate winter skills and equipment.

Summit and views

The main summit cairn is at NN38688 32227. The South Top is at NN38640 31570, where the recorded high point is a boulder just west of its cairn. Reaching that lower top does not complete the ascent of Ben Challum.

In clear conditions, the route and summit ridge offer views of Ben Lui, Ben More and Stob Binnein, Strathfillan and Glen Lochay.

Geology and name

The Ben Challum–Tyndrum area contains Dalradian metamorphic schists and quartzites. The Ben Challum Quartzite lies between the Ben Lawers and Ben Lui schists. These are metamorphosed sedimentary rocks.

Beinn Chaluim means “Calum/Malcolm’s mountain”. The name alone does not identify a particular historical person.

Access and facilities

Parking in the A82 layby is limited; do not obstruct access or assume the working farm provides parking. Citylink coaches and rail services reach Crianlarich and Tyndrum, but these village stops are separate from the walk’s start. Plan onward access and check your travel date and last return service.

Crianlarich has refreshments and public toilets. Check opening times before relying on them. There are no facilities on the mountain or at the layby.
