An Stac, Sgurr na Ba Glaise and Rois-Bheinn

This is a big, serious Moidart mountain day: roughly 17 km / 10.6 miles with about 1,500 m / 4,920 ft of cumulative ascent, taking in three rugged Corbett summits on a compact but demanding circuit. The ground is varied almost from the outset, with estate tracks, wet and peaty sections, steep grassy pulls, rocky ridge walking, and a couple of places where careful foot placement matters more than speed. Although the highest summit, Rois-Bheinn, is only 882.4 m / 2,895 ft, it rises close to sea level and feels much bigger than the number suggests. The ridge linking Sgùrr na Bà Glaise, Rois-Bheinn and An Stac is widely regarded as one of the finest Corbett outings on the mainland, with expansive views over the Sound of Arisaig and toward Eigg and Rum on clear days.

The usual start is near the minor road for Glen Shian off the A861, close to Kinlochmoidart and the salmon hatchery entrance rather than at the older informal spots where parking is discouraged. A practical landmark for navigation is the Glen Shian turning on the A861 near Kinlochmoidart, with nearby approach parking described on the verge of the track leading toward the hatchery. Another nearby reference point for the area is Ardmolich on the A861, about 2 miles / 3.2 km south of Kinlochmoidart, with postcode PH38 4ND given as the nearest sat-nav reference for that locality.

By car, most walkers approach via the A861 through Moidart, either from Fort William or from the A830/Lochailort side depending on where they are based. Roads in this area are scenic but slow, narrow in places, and passing-place etiquette is essential. Parking is limited and informal, so an early arrival is wise, especially in summer.

Public transport is possible but requires planning. Buses on the Fort William–Acharacle corridor stop at Kinlochmoidart (Postbox), which is the most useful nearby stop for the walk-in, though services are limited and not frequent. Forestry and Land Scotland also notes daily buses except Sunday through Ardmolich on the same general corridor. Because this is a long difficult hill day in a remote area with weak or no signal reported on the hill, it is important to check the latest timetable before committing and to build in a generous margin for the return.

Lower approach

The opening section is not especially dramatic, but it sets the tone for the day. From the roadside start, the route heads past cottages and onto a grassy track through gates, with the salmon hatchery nearby. The early ground can be waterlogged, and there is a choice between a more direct but wetter line through woodland and bealach ground south of Tom Odhar, or a slightly longer, drier line using the hydro track around the north and east sides of Tom Odhar. Either way, expect damp boots early unless conditions have been very dry. (walkhighlands.co.uk)

After the tracks rejoin, the route crosses the Allt a’ Bhuiridh and begins to climb more decisively. This is where the day starts to feel strenuous. The ascent onto Meall Damh and then toward Druim Fiaclach is steep and can be tiring when the ground is greasy. The terrain shifts from rough grass and ATV track to rockier ridge ground, and the sense of remoteness increases quickly. Hikers should be ready for bog, heather, and uneven footing on the lower slopes, with bracken and ticks a known issue in summer. (walkhighlands.co.uk)

Ridge to Sgùrr na Bà Glaise

Druim Fiaclach is not one of the named headline summits in your route title, but it is one of the most memorable parts of the outing. The ridge is rocky, narrow in feel without being technical in normal dry conditions, and gives a superb first real panorama over the broken coastline and the wild interior of Moidart. From there the route drops steeply to Bealach an Fhaslaigh Dhuibh before climbing
