Loch na Gainmhich, Eas a' Chual Aluinn, Loch nan Caorach and Stack of Glencoul

This is a long, wild Assynt circuit that links one of Britain’s most dramatic waterfalls with a superb outlying summit above Loch Glencoul. At around 24 km / 15 miles with roughly 1,000 m / 3,280 ft of ascent, it is better thought of as a serious mountain day than a moderate stroll, even if the technical ground is mostly non-climbing. The terrain is remote, often rough underfoot, and can feel much bigger than the numbers suggest because progress across the rocky, boggy plateau is slow. The start is the parking area on the A894 at the sharp bend near the north end of Loch na Gainmhich, about 4 km / 2.5 miles south of Unapool and a short drive east-southeast of Kylesku. Walkhighlands gives this same roadside start for the standard approach to Eas a’ Chual Aluinn, with grid reference NC239292. (walkhighlands.co.uk)

From the road, the route quickly leaves behind any sense of easy access. The first section near Loch na Gainmhich is known for being wet and peaty, with rough, indistinct trods rather than a built path. Even on a dry spell, expect soft ground, hidden holes, and sections where line choice matters. The landscape opens fast, though, and the reward is immediate: Quinag rises behind, Glas Bheinn stands off to one side, and the route begins to feel properly remote. The standard path toward Eas a’ Chual Aluinn climbs by Bealach a’ Bhuirich and reaches a high point of about 450 m / 1,476 ft before descending toward the burn above the falls; on this larger circuit, that approach forms the first major leg before the route continues onward toward Loch nan Caorach and the Stack of Glencoul.

Terrain and what to expect

The outing naturally breaks into four character changes: the boggy lochside approach, the stony pass and upland lochans, the dramatic waterfall section, and the broader hill circuit around Loch nan Caorach to the Stack of Glencoul. The first few kilometres are often the messiest underfoot. After that, the ground becomes rockier and more defined, but never especially fast. Assynt’s ancient Lewisian gneiss creates a hard, knobbly surface with endless ribs, shelves, and broken outcrops, so even where the map looks simple, the walking can be tiring. Walkhighlands specifically notes very boggy ground near the start and rough, rocky terrain beyond, and also highlights that the rocks here are Lewisian gneiss, among the oldest on Earth.

The waterfall section is the psychological midpoint for many hikers. Eas a’ Chual Aluinn drops about 200 m / 656 ft in two main stages into the deep trench above Loch Glencoul, and it is widely described as the highest waterfall in the UK. The best viewpoint is not at the very lip, but from a lower, offset vantage reached by following the safer line described on the established approach. The cliff edges here are serious. Walkhighlands warns that the lip gives only a limited view and that fatalities have occurred in the area, so this is not a place for casual edging forward in wind, rain, or mist.

Beyond the falls, the route becomes more committing. The line toward Loch nan Caorach and the Stack of Glencoul crosses open hill country where paths can be faint, intermittent, or absent. In clear weather, the navigation is manageable for experienced hillwalkers, but in mist the terrain can become confusing because of the many lochans, shallow basins, and rocky undulations. For planning and on-the-ground navigation, use HiiKER and still carry the skills and backup needed for a remote mountain route. This is a place where poor visibility can slow the day dramatically.

Landmarks, scenery, and geology

Loch na Gainmhich is the first major landmark and sets the tone for the day: a lonely loch tucked beneath rough hills, with the route skirting its northern side. The name reflects the Gaelic word for sand, a reminder that place-names in the
