Lochan a' Choire, Stob Poite Coire Ardair, Creag Meagaidh, Puist Coire Ardair and Sron a' Choire Loop from Loch Laggan

This is a big Highland circuit with a serious mountain feel despite its medium rating on paper. At roughly 18 km / 11.2 miles with around 1,000 m / 3,280 ft of ascent, it asks for stamina, steady footing, and enough mountain sense to deal with fast-changing weather on broad, exposed tops. The route is generally associated with the Creag Meagaidh National Nature Reserve car park at Aberarder, on the north side of the A86 by Loch Laggan, with the nearest usable address commonly given as Creag Meagaidh, Aberarder, Kinlochlaggan, PH20 1BX.

From the start, the route heads into one of the most dramatic corries in the Central Highlands. The early section is usually the most straightforward: estate tracks and clear hill paths lead through regenerating woodland and open glen terrain toward Coire Ardair. This lower approach is a good warm-up rather than a trivial stroll, covering several kilometres before the mountain really begins to bite. Expect the first 4 to 5 km / 2.5 to 3.1 miles to feel relatively efficient underfoot, with moderate climbing as the glen narrows and the cliffs ahead begin to dominate the skyline. The reserve has seen major habitat restoration and woodland expansion around the lower glen, so the approach is not just a means to an end; it is part of what makes this walk distinctive.

Approach to Lochan a' Choire

The route’s first major landmark is Lochan a' Choire, tucked beneath the vast cliffs of Coire Ardair. This is one of the visual highlights of the day and a natural place to pause, check layers, and assess conditions higher up. The corrie is glacial in origin, and the landscape has a classic amphitheatre shape: steep rock walls, a dark lochan, and a sense of enclosure that becomes more dramatic as you draw closer. Walkhighlands describes the lochan as appearing at the last moment beneath the spectacular cliffs, which is exactly why this section feels so memorable. (walkhighlands.co.uk)

Although the path to the lochan is well known and often clear, this is where the outing starts to become more committing. Beyond the lochan, the terrain steepens and the route options become more mountain-specific. If your loop includes Stob Poite Coire Ardair, Creag Meagaidh, Puist Coire Ardair, and Sròn a' Choire, expect rougher ground, steeper gradients, and more need for careful line choice than on the lower approach. HiiKER is the navigation tool to rely on for checking the exact line of the loop and confirming where the route leaves the main corrie path. (ukhillwalking.com)

The Climb and High Ground

The ascent from the corrie toward the high ridge is the crux of the day. Paths here can be steep, loose, bouldery, and tiring, especially if the route climbs toward The Window, the well-known col between Stob Poite Coire Ardair and Creag Meagaidh. This pass is one of the classic access points onto the massif, but it can hold snow and feel much more serious in poor conditions. Even outside winter, mist and wind can make the upper mountain feel complex and exposed. (walkhighlands.co.uk)

Once on the tops, the character changes from enclosed corrie walking to a broad, elevated circuit with long views over Loch Laggan and the surrounding Highlands. Stob Poite Coire Ardair rises to about 1,054 m / 3,458 ft, while Puist Coire Ardair reaches about 1,071 m / 3,513 ft; both are substantial high points rather than minor bumps on a ridge. The ridge linking these summits with Creag Meagaidh and Sròn a' Choire gives the walk its full mountain-day quality. Distances between tops are not huge, but the ground can be energy-sapping, and in cloud the broad plateau and connecting ridges can feel less obvious than they do on a clear day. (en.wikipedia.org)

Creag Meagaidh itself is the dominant summit of the group and the mountain that gives the reserve its name. The massif sits above Loch Laggan and is often treated as one of
