Although one can climb Ben Challum on its own, a fine round is achieved by including the
two Corbetts Beinn Chaorach and Cam Creag.
The price tag is a mere 440m=1500' extra ascent and three miles more distance,
yielding a total which is still just an average day.
With such a round there's a greater variety of scenery, and the crossing from
Cam Creag to Ben Challum is unusually enjoyable. It also saves
a lot of climbing if you were ever to return to do the Corbetts.
There are several possible parking spots to start from. The best is by Auchtertyre Farm at NN35312901, but there is also parking on the west side of the A85 by Dalrigh at NN34362914 and by Auchreoch at NN35612812. The West Higland Way all but connects these three choices.
The railway needs to be crossed. This is possible by taking the road on either side of the river under the viaduct at Auchtertyre or by the footbridge at NN36182871.
Route: This route includes Beinn Chaorach, Cam Creag and Beinn Challum, starting at Auchtertyre.
I strongly recommend tackling this in a clockwise direction to avoid finishing
by walking through the deep cattle excrement
all over the track at the SW corner of the viaduct.
Conditions: Dry all day but stiff breeze.

Route: This is just Ben Challum, starting at Dalrigh and returning by the outward route.
Weather: Wind, low clouds, rain. Snow under foot above 2000'.
Comments: Better to park in designated car park at Auchtertyre Farm, and take track on West bank of river as far as N end of forestry, then cross river by bridge & take track up E bank to dam (not marked). An alternative, given below, is to go via Kirkton Farm and over a level crossing above the farm, from which there is a path up the ridge to the summit.
