Bidein Toll a' Mhuic, Stob a' Choire Liath Mhor, Spidean a' Choire Leith, Am Fasarinen and Mullach an Rathain Loop

This is a serious mountain day in Torridon, with roughly 12 km / 7.5 miles of travel and about 1,200 m / 3,940 ft of ascent packed into a compact but relentlessly steep circuit. Despite the moderate distance on paper, the terrain makes it feel much bigger: long, sustained climbing, rough and rocky ground, narrow ridge sections, and frequent exposure. Anyone planning this route should treat it as a full mountain outing rather than a simple half-day walk.

The route is generally associated with the Liathach massif above Glen Torridon, and the nearest well-known starting point is usually around the A896 near Torridon village, close to the Liathach roadside lay-bys and the area around Torridon Youth Hostel / Torridon Inn. If you have coordinates from another source, the practical landmark to look for is the A896 roadside beneath Liathach on the north side of Upper Loch Torridon. That is the usual access zone for ascents of this ridge.

Getting there by car is the simplest option. Most walkers approach via the A896 through Glen Torridon, with parking typically limited to roadside lay-bys, so arriving early is wise, especially in the main hiking season. Roads in the area are scenic but slow, with single-track sections common in the wider region, so journey times are often longer than they appear on a map.

Public transport is much more limited and requires planning. The nearest larger hubs are typically Inverness or Kyle of Lochalsh, from which bus connections run toward Torridon or nearby villages on limited schedules. Services in Wester Ross can be infrequent and may not line up well with a long mountain day, so anyone relying on buses should check current timetables carefully and build in a backup plan. For navigation on the hill itself, use HiiKER alongside your usual mountain planning.

The climb begins brutally by Highland standards: there is very little gentle easing-in. From near road level, the route rises quickly onto the lower slopes of Bidein Toll a’ Mhuic, and much of the first part of the day is a steep grind on rough, often loose ground. In wet weather, the lower path can be greasy and tiring, and after rain the rock higher up may become much more serious. Even early on, the views open dramatically over Glen Torridon, Beinn Eighe, and the sea lochs to the south and west.

The ascent and ridge character

The first major objective, Bidein Toll a’ Mhuic, is not just a warm-up top. Reaching it involves a substantial share of the day’s climbing, and the ground can feel awkward underfoot, with boulders, eroded sections, and steep lines that demand steady pacing. Expect the first few kilometres to be slow. A useful mental guide is that the route’s difficulty comes less from mileage and more from how concentrated the effort is.

From there, the traverse toward Stob a’ Choire Liath Mhòr and Spidean a’ Choire Leith becomes increasingly dramatic. This is classic Torridon terrain: ancient sandstone, shattered rock, abrupt drops, and a ridge that often feels far bigger than the map suggests. On clear days, the panoramas are exceptional, stretching across Loch Torridon, the Applecross hills, the Fisherfield mountains, and the wider Northwest Highlands. In poor visibility, however, the same ridge can become confusing and committing, especially where lines split around rocky obstacles.

The section around Spidean a’ Choire Leith, Liathach’s highest summit, is one of the great mountain positions in Scotland. The ridge architecture here is striking, with huge corries dropping away and a real sense of exposure. Strong winds can make progress difficult, and in cloud the route-finding demands care. This is not terrain for casual wandering off line.

The continuation toward Am Fasarinen and Mullach an Rathain keeps the day serious. Although some walkers think the hardest work is over once the main summit is reached, the ridge still requires concentration. Fatigue becomes a factor here, especially on uneven rock where a stumble could have consequences. If the route includes the famous pinnacled ridge sections nearby, some parties may choose to avoid the most technical ground depending on conditions and confidence, but even the easier line remains a demanding mountain traverse.

Terrain, hazards, and what to expect

This is best suited to experienced hillwalkers comfortable on steep, rocky, exposed mountain ground. The “Extra Difficult” rating is justified not because the route is exceptionally long, but because it combines several serious factors at once:

• Steep ascent from the outset
• Rough, energy-sapping terrain
• Exposure on ridge sections
• Potential scrambling or hands-on movement
• Complex navigation in mist
• Rapidly changing mountain weather

Allow more time than the distance suggests. For many parties, 12 km / 7.5 miles here can take as long as a much longer low-level walk. Average pace may drop sharply on the ridge, especially in wind or rain.

In dry, calm weather, the rock can feel secure and enjoyable. In wet or icy conditions, the route changes character completely. This is not a good choice in high winds, winter conditions, or poor visibility unless everyone is properly equipped and experienced. Snow or verglas on the ridge can turn a hard walk into a mountaineering outing.

Waterproofs, warm layers, gloves, and emergency kit are essential even in summer. There may be little shelter once high on the ridge. Trekking poles can help on the lower ascent and descent, though they are often stowed on the rockier sections
