Ruadh-stac Mor: the Rocky Peak of Beinn Eighe

Ruadh-stac Mòr, meaning "big red stack" in Gaelic, is a remote and rugged Munro nestled in the heart of the Fisherfield Forest, often referred to as Scotland's "Great Wilderness". At 918 metres, it is not the tallest peak in the area, but its russet boulderfield summit and incredible remoteness make it a coveted prize for seasoned hillwalkers. This is a strenuous undertaking that demands careful planning, as the mountain is typically accessed through multi-day routes involving long approaches, wild camping, or bothy stays. If you're looking for a true adventure in one of the most unspoiled landscapes in the British Isles, Ruadh-stac Mòr is a challenge worth embracing.

Contrary to some confusion in older reports, Ruadh-stac Mòr is not part of the Beinn Eighe massif in Torridon. Instead, it lies deep within Fisherfield, far from the road and surrounded by an arresting panorama of lochs, craggy peaks, and vast expanses of bogland. This guide will equip you with everything you need to know to tackle this remote Munro and fully enjoy the experience.

Route Overview

Ruadh-stac Mòr is most often climbed as part of the Fisherfield "Big 6" circuit, a gruelling route that includes five Munros and one Corbett. However, walkers can also target it as a standalone ascent, often paired with A' Mhaighdean, another Munro in the area. Expect boggy terrain, steep scrambles, and breathtaking views of Scotland's wildest landscapes.

• Distance: Approximately 44 km for the full circuit, or 12 km return from Carnmore bothy.
• Ascent: Around 2,905 metres for the full Big 6, or 975 metres from Carnmore bothy.
• Time: 12+ hours for the full circuit or 4-5 hours for a shorter outing from Carnmore.
• Difficulty: Strenuous - navigation skills and a high level of fitness are essential.

The most popular starting points are from Shenavall bothy, Carnmore bothy, or Poolewe/Kernsary. Below, we outline the key stages of the walk via Shenavall, which is the most widely used route.

The Walk

Stage 1: Approach to Shenavall Bothy

The journey begins at Corrie Hallie, just off the A832 near Dundonnell. A rough track leads through boggy terrain and past the edge of woodland, eventually descending to the picturesque Shenavall bothy. This approach is approximately 6.5 km and takes 2-3 hours. Many walkers choose to stay overnight here before tackling the Fisherfield Munros. Shenavall is a basic but welcoming bothy, with stunning views of the surrounding peaks.

Stage 2: Crossing the Pollan na Muice River

From Shenavall, cross the Pollan na Muice river (bridge-free, so care is needed in high water) and follow a stalkers' path past the western slopes of Beinn a' Chlaidheimh. The path climbs steadily towards the bealach south of A' Mhaighdean. This section is about 8 km and can be energy-sapping due to boggy ground. Keep an eye on your map and compass as the terrain can be disorienting in poor visibility.

Stage 3: Scramble to the Summit

From the bealach, a rough and loose scramble begins up the western ridge of Ruadh-stac Mòr. The terrain is steep, with some Grade 1 scrambling required to negotiate the boulderfield and crags. Take care on this section, especially in wet or icy conditions. The summit rewards your efforts with awe-inspiring vistas of the Fisherfield Forest, the shimmering lochs below, and the distant peaks of An Teallach and Torridon.

Stage 4: Descent and Return

Retrace your steps carefully to the bealach and either return to Shenavall by the same path or continue your adventure by tackling other Munros in the Fisherfield circuit. If time and energy allow, combining Ruadh-stac Mòr with A' Mhaighdean makes for an unforgettable day.

Getting There and Parking

The most common access point is Corrie Hallie on the A832, where limited parking is available. Alternatively, some walkers start from Poolewe or Kinlochewe if approaching from the west. Note that these approaches involve even longer distances to reach bothies or campsites. Carnmore bothy offers a closer starting point for Ruadh-stac Mòr, but reaching it requires a challenging bike or foot journey via Poolewe and Kernsary.

Public transport options are limited in this remote area, so driving is recommended. Always check seasonal access restrictions, particularly during the deerstalking season. The Scottish Outdoor Access Code provides helpful guidance for responsible access in these areas.
