Spidean Coinich and Sail Gharbh Loop

This is a rugged mountain circuit on Quinag in Assynt, a compact but serious outing of about 10 km / 6.2 miles with roughly 800 metres / 2,625 feet of ascent. Even though the distance is modest, the effort is not: the climb is steep, the ridge terrain is rough in places, and poor weather can make the route feel much bigger than the numbers suggest. Expect a long, sustained ascent from low ground, a high bealach, and a dramatic ridge walk to two of Quinag’s best-known summits, Spidean Coinich and Sail Gharbh. The usual start is the Quinag car park on the east side of the A894, about 2.75 km north of Skiag Bridge, near Unapool, Lairg, Sutherland. Sources describing this route place the start at grid reference NC232273, with a car park directly off the A894. (johnmuirtrust.org)

The approach begins on a well-built path across moorland, and that early section can lull people into thinking the day will be straightforward. It is not. The path is generally clear and maintained, but the mountain rises abruptly from the surrounding peatland, so the route quickly turns into a sustained climb. The lower ground is often wet, especially after rain, and the mountain’s coastal position means wind, mist, and rain can move in fast. The John Muir Trust specifically notes the restored main footpath and the need to avoid shortcuts across fragile peat, while also warning that conditions change quickly in this environment.

What the route feels like

From the car park, the path heads west toward Quinag’s eastern flank, with Spidean Coinich’s pointed profile drawing the eye. The first few kilometres are a steady build-up over moor and stony path before the gradient bites harder on the climb toward Bealach a’ Chornaidh, the main saddle at around 570 metres / 1,870 feet. On a route of roughly 10 to 11 km / 6.2 to 6.8 miles, this bealach is the key turning point in the day, because it gives access to both summits and marks the transition from path walking to more mountainous ridge terrain.

Spidean Coinich, the southern summit, stands at about 764 metres / 2,507 feet, while Sail Gharbh, the higher northern summit on this loop, reaches about 808 metres / 2,651 feet. The ridge between them is the highlight of the outing: airy in feel, rocky underfoot, and highly scenic in clear weather. Some route descriptions mention easy scrambling steps and exposed situations on Quinag’s ridges, so this is a hike where hands may occasionally be useful for balance, especially in wet or windy conditions. It is not a technical scramble in normal summer conditions, but it is definitely more serious than a simple hill path. (thegreatoutdoorsmag.com)

The climb to Sail Gharbh from the bealach is particularly steep. One published route description notes a very steep ridge with a few easy scrambling steps leading to an unnamed high point before the final ridge to Sail Gharbh. That section is where many hikers will feel the “Difficult” rating most strongly: the ascent is abrupt, the ground is rocky, and in cloud the terrain can feel confusing. If visibility drops, careful line-finding matters, and HiiKER is the navigation tool to have prepared in advance. (thegreatoutdoorsmag.com)

Landmarks, views, and terrain

Quinag is famous for its shape. Its Gaelic name, A’ Chuinneag, is commonly translated as “the milk pail,” a reference to the mountain’s distinctive form. The massif has three main Corbett summits, and this loop focuses on two of them. From the ridge, the landscape opens across Assynt’s extraordinary mix of lochs, isolated peaks, and sea-facing horizons. In clear weather, walkers can expect wide views over Loch Assynt, the surrounding Sutherland hills, and westward toward the Minch and the Isle of Lewis. (johnmuirtrust.org)

Geologically, this is one of the most interesting mountain areas in Scotland. Quinag sits within the North West Highlands Geopark, and the mountain displays Torridonian sandstone over much older Lewisian gneiss, with younger Cambrian quartzite capping parts of the higher ridge, including areas around Sail Gharbh and Spidean Coinich.
