Deep immersion in the Great Wilderness
The Letterewe Forest, commonly known as Fisherfield, is the most isolated landmass on the British mainland. Defined by its lack of roads, trees and easy exits, this is a landscape of significant river crossings, trackless glens and a level of remoteness that is rare even in Scotland.
Our expedition targets the Fisherfield Six, including A’ Mhaighdean, in a calm, conditions-led 4-day journey with realistic pacing. This is one of the strongest routes in the UK for anyone wanting to understand what real expedition distance and commitment feel like.
If you are comparing shorter and longer Scottish routes, the guided wilderness expeditions hub gives a useful overview of the wider Peak Adventures programme. For broader planning, camp craft and route-thinking, read our guide to wild camping in the UK.
Why this route?
Fisherfield is the definitive test of Scottish remoteness: long walk-ins, committing ground and rivers that can dictate the day. We use a 4-day line to respect the distance and give enough margin for good decisions, rather than rushing one of the most serious mountain landscapes in the UK.
You also learn the practical nuances of expedition travel here, from reading spate risk to choosing sheltered camps and moving efficiently with a multi-day pack. It is one of the best environments in Britain for learning what true mountain self-sufficiency feels like.

One of the UK’s most serious mountain journeys
Fisherfield occupies a special place in British mountain travel because it is defined by absence: no roads, few shortcuts, very limited escape options and a level of commitment that builds with every mile. For walkers searching for a guided wilderness expedition in Scotland that feels genuinely remote, Fisherfield is among the strongest routes available.
What makes the expedition so compelling is not only the mountain list, but the ground between the summits. River crossings, camp selection, weather judgement and the long, reflective distances all shape the experience. The result is a journey that feels bigger than its duration and far more serious than a typical backpacking route.
For those progressing toward longer mountain expeditions, Fisherfield offers a defining step: more committing than a taster trip, logistically richer than a simpler traverse and full of the navigation, pacing and campcraft that matter most in real wilderness travel.
The journey (4 days)
A committed progression: walk-in to Shenavall, deep interior travel, then a long trek out. Questions before booking? See our wild camping FAQs.
Day 1
Shenavall & the gateway
⌄
From Corrie Hallie we cross moorland to the iconic Shenavall bothy area. We camp here on the edge of the true wilderness, positioning carefully for river crossings and deeper interior travel on the following days.
Day 2
The big river & first Munros
⌄
Crossing the Abhainn na Fuirneis, we enter the Empty Quarter. When conditions allow, we begin linking the first mountains of the expedition before establishing a remote camp deep in the interior near Fuar Loch Mòr.
Day 3
A’ Mhaighdean & the remote view
⌄
A defining mountain day. A’ Mhaighdean offers an unparalleled view across Letterewe to the Atlantic, the kind of perspective only true remoteness delivers. A final high-wilderness camp follows, with the sense of distance now fully established.
Day 4
The reflective trek out
⌄
A long but rewarding journey back through trackless glens to Corrie Hallie, with time to absorb the scale, silence and distance of the previous four days. The exit is part of the experience, and part of what makes Fisherfield so memorable.
