Kinloch Hourn to Barisdale via Loch Beag, Caolas Mor and Barrisdale Bay

This is a remote coastal Highland walk with a wild feel far bigger than its numbers suggest. Although the outing is around 20 km / 12.4 miles with roughly 600 m / 1,970 ft of ascent, the terrain, isolation, and repeated ups and downs along Loch Hourn can make it feel more demanding than a typical “medium” day. The route begins at Kinloch Hourn, the tiny settlement at the head of Loch Hourn, reached by a long single-track road from the A87 near Invergarry. Kinloch Hourn is the main recognised trailhead and road end for this walk. Loch Hourn itself runs about 22 km / 14 miles inland and is often described as one of Britain’s most fjord-like sea lochs, which gives the whole route its dramatic character. (en.wikipedia.org)

From the start, the path heads west along the south side of the loch, never letting you forget that this is sea-loch country rather than an inland glen. Expect a rough, undulating track rather than an easy shoreline stroll. The first few kilometres rise and fall above rocky inlets and steep slopes, with frequent short climbs that steadily add to the day’s total ascent. Even when the map suggests a fairly direct line, progress can be slower than expected because sections of the old path are stony, narrow, wet, or eroded. HiiKER is the navigation tool to rely on here, especially in poor visibility or if the path becomes faint around rougher ground. (hiiker.app)

Along Loch Beag and Caolas Mòr

As the route develops, the landscape becomes a sequence of headlands, coves, and open views across the water to the steep northern mountains. Around Loch Beag and onward toward Caolas Mòr, the walk feels particularly rugged and coastal, with the path weaving around the contours rather than forcing a straight passage. Approximate distances can be deceptive here: a 3 km / 1.9 mile section may take longer than expected because of uneven footing and constant minor ascent and descent. The cumulative climb is usually felt most in these middle stretches, where the route repeatedly gains height above the loch before dropping again toward burns and bays. (walkhighlands.co.uk)

The scenery is one of the route’s great rewards. Across the water, Beinn Sgritheall dominates many views, while farther west the mountains around Barrisdale and the interior of Knoydart begin to open out. Barrisdale Estate notes the surrounding skyline includes Ladhar Bheinn, Luinne Bheinn, and Meall Buidhe, and these peaks help give the final approach a grand, mountain-ringed setting.

Nature is a major part of the day. Knoydart is known for birch woodland on steep glen sides, patches of Caledonian pinewood around Barrisdale, and wildlife including red deer, otters, pine martens, buzzards, golden eagles, and sea eagles. Along the loch edge, keep an eye out for seabirds and for movement on the water, while the slopes above often hold deer. Midges can be a serious nuisance in still, damp weather, especially near burns, woodland edges, and around the bay at the end of the route. (en.wikipedia.org)

Final approach to Barrisdale Bay

The last section eases into the broader landscape around Barrisdale Bay, where the route becomes more open and the sense of arrival grows. Barrisdale is a small settlement and estate on the bay, with a bothy and campsite used by walkers. Some route descriptions place the walk-in from Kinloch Hourn at about 11 km / 6.8 miles one way, so a full out-and-back day or a longer variation via shoreline features can bring the total close to the 20 km / 12.4 mile distance you are planning for.

Barrisdale Bay is one of the classic gateways into Knoydart, a peninsula long regarded as one of the most remote parts of mainland Britain. Historically, this region carries layers of Norse influence, clan history, estate management, droving, and later the transformation of land into large sporting estates and deer forests. Sources on Loch Hourn and Knoydart note that the south shore of Loch Hourn and Barrisdale formed part of the old Knoydart lands, and
