NG9579345069 Set off up the Fionn-abhainn glen. You'll pass a bungalow and gain a good stalkers' track heading upriver. Once you're established on this, it's hard to go wrong. Cross the footbridge over the Fionn-abhainn, then pass the curious memorial to Breton father and son Michel and Alan Conan, the Coire Fionnaraich bothy and the boulder of Clach nan Con-fionn, where Fionn the giant tethered his hounds. Or so it is said.

NG9482349011 Turn left at an easily-located junction to pick up a strong set of stalkers' zigzags on striking white gravel.

NG9314448806 Get ensconced in the complex col of Bealach a Choire Gharbh with its three radial ridges and three descents; this would not be a good place in mist. Get acquainted with the lie of the land, because this is your first of three visits to this point today. Head northwest up rough slopes to the fine Munro of Maol Chean-Dearg.

NG9239949903 Reverse your footsteps down to the bealach. Set off on your second out-and-back expedition heading east-south-east on improbable-looking slabby terrain to the fine summit of An Ruadh-stac. It is scrambly but, in dry weather at least, manageable with care.

NG9213648037 Avoid all temptation to go off-piste, which would plunge you into vast realms of knee-deep bouldery heather, never to be heard from again. Instead, return via the stalkers' tracks whence you came. On the zigzags down from the bealach, your knees will thank you.
