Fisherfield Round

ScramblingGrade details

Grades describe the named technical sections, not every metre of the route.

Route overview

Deep within the Letterewe wilderness, this classic round traverses some of the most remote mountains in the Highlands. Starting from Shenavall, the route tackles five Munros and one Corbett, offering unparalleled ruggedness, dramatic ridge lines, and legendary views over the Fionn Loch. It is an exceptionally demanding outing reserved for fit, self-sufficient hillwalkers seeking a true test of endurance.

Terrain and underfoot

The terrain is exceptionally rough and varied, featuring steep heather, extensive quartzite boulder fields, and narrow ridges with minor scrambling. Path quality is highly variable, with faint trails on the high plateaus and a notorious, waist-deep bog in the glen. Crucially, the route requires three major river crossings, including the Abhainn Strath na Sealga, which are dangerous or entirely impassable when water levels are high or in spate.

Driving and parking

Corrie Hallie and Shenavall

Corrie Hallie has small roadside parking for the approach into Fisherfield. The GPX circuit starts and ends at Shenavall, not at the road: its 29.7 km excludes the approach from Corrie Hallie. Keep the road, passing places and access tracks clear.

A small roadside recess at Corrie Hallie. This is approach parking, not the start of the GPX circuit at Shenavall.

Before you go
Shenavall bothy is unavailable from 15 September to 20 October during stag stalking. This applies to the bothy, rather than a blanket closure of the surrounding hills.
Walking approach and return
A workparty is scheduled for 21 to 25 October 2026 and may cause disruption at Shenavall. Check the MBA notice before depending on the bothy.

Beinn Tarsuinn · Mullach Coire Mhic Fhearchair

Beinn Tarsuinn and Mullach Coire Mhic Fhearchair

Route overview

This exceptionally long and demanding expedition penetrates deep into the wild Fisherfield Forest to claim two distinctive Munros. Starting from Incheril, the route follows a lengthy approach past Lochan Fada before tackling the grassy slopes of Beinn Tarsuinn and the rugged, quartzite-capped dome of Mullach Coire Mhic Fhearchair. It offers an immersive, remote mountain experience for fit walkers.

Terrain and underfoot

The walk begins on excellent estate tracks, which can be cycled to ease the long approach. Beyond the tracks, the terrain becomes increasingly rough, wet, and faint. The ascent of Beinn Tarsuinn is largely on grassy slopes, whereas Mullach Coire Mhic Fhearchair demands a steep climb over rough sandstone and loose quartzite boulder fields. Navigating the high, pathless sections requires competence, and several burn crossings may become difficult after heavy rain.
