Mullach Coire Mhic Fhearchair

Mullach Coire Mhic Fhearchair, at 1,018-1,019 metres, is the highest of the Fisherfield Munros, an extremely remote peak in the Great Wilderness, added to by the sheer length of any approach and the difficulty of walking a ridge covered in angular quartzite boulders.

Most walkers reach this summit as part of the celebrated "Fisherfield Round," starting from Corrie Hallie or Incheril, typically via Shenavall bothy or a wild camp. From Sgùrr Bàn, a steep and eventually well-defined path crosses a col before a steep, rocky ascent — remarkable for how much loose sand and shingle covers the slope, at times feeling like walking up a sand dune — leads to the summit, marked by only a small cairn on a compact top. The views here are widely regarded as the highlight of the whole round, taking in the dramatic landscape of corries, lochs, and distant peaks throughout Fisherfield.

An alternative approach from the south, via Incheril and Lochan Fada, gives easy walking initially before becoming progressively rougher, with a faint path up to the bealach below Meall Garbh — that peak looks a formidable obstacle but has a bypass path on its northern side, leading to a slightly higher bealach beyond, from where the ascent of Mullach Coire Mhic Fhearchair begins in earnest, first up a sandstone ridge before the steepest upper section crosses slow-going quartzite boulders.

From the summit, the descent towards Beinn Tarsuinn involves a long, sweaty reascent for those approaching from that direction, or a challenging, sometimes snow-affected ridge continuing to Sgùrr Bàn for those completing the full round in the opposite direction.

The full Fisherfield Round taking in all five Munros — Sgùrr Bàn, Mullach Coire Mhic Fhearchair, Beinn Tarsuinn, A' Mhaighdean, and Ruadh Stac Mòr — from Corrie Hallie is a genuinely epic undertaking, typically requiring an overnight stay at Shenavall bothy or a wild camp, with total walking times often exceeding sixteen hours across the full distance.

This is committing, remote terrain with potentially dangerous river crossings on the approach and genuinely difficult navigation on the boulder-strewn ridges in poor visibility — full self-sufficiency, navigation skills, and realistic fitness assessment are all essential given the isolation involved.

There is no direct parking at the mountain itself; Corrie Hallie or Incheril car parks serve as the main starting points, both free, with limited public transport connections.
