Gillaval Dubh, Giolabhal Glas, Beinn na Teanga, Sron a' Sgaoth and Loch a' Siar Loop

This 16 km (10 mile) loop in North Harris is a compact but serious hill day, climbing roughly 800 m (about 2,625 ft) over a chain of rounded yet rugged summits above Loch a’ Siar and Gleann Lacasdail. The route is often associated with the Skeudale Horseshoe, a fine circuit of hills south of the A859, and it links Gillaval Dubh, Giolabhal Glas, Beinn na Teanga, Sròn a’ Sgaoth and the surrounding ridges in a broad arc with constant views over sea lochs, moorland and the rocky Harris interior. The terrain is varied rather than technical: steep grassy pulls, sections of rockier ridge, broad summit ground, wet moor, and some rough heather lower down. Although the overall difficulty is often considered medium, it can feel harder in poor visibility, after rain, or in strong Atlantic wind because paths are intermittent and the ground can be slow.

The start is best described as near Ceann an Ora bridge on the A859, close to Ardhasaig, Isle of Harris, HS3 3AJ, which is the most useful nearby landmark for planning arrival. Visitor information for the Skeudale Horseshoe places the walk at Ardhasaig, and the route begins from the bridge at Ceann an Ora before climbing steeply onto the northern ridge.

By car, the usual approach is via the A859 between Tarbert and the North Harris side of the island, using a small roadside pull-in near the bridge if space and local access allow. Care is needed not to block passing places, gates, croft access or estate traffic on this narrow road. Tarbert is the main service hub nearby for fuel, food and accommodation, so it is the sensible place to make final preparations before heading out. For public transport, Tarbert is the key connection point on Harris, and buses serve the A859 corridor; the wider Hebridean Way information confirms bus-served access on this side of Harris, though timetables should be checked carefully because services can be limited.

What the ground is like

The opening climb is one of the more demanding parts of the day. From Ceann an Ora, the ascent to Gillaval Dubh rises steeply on grassy slopes and through a rocky band, quickly gaining height above the road. That first effort is rewarded by a more open ridge walk, and much of the circuit beyond is over comparatively easy hill ground by Hebridean standards, though “easy” here still means uneven, pathless country where peat, heather and wet patches can sap energy. The ridge running southeast toward Giolabhal Glas is generally straightforward, with expansive views and a good sense of the horseshoe shape around the Skeudale valley. (visitouterhebrides.co.uk)

Expect the first few kilometres to do most of the work. A useful planning assumption is that the climb to the first high ground comes early and decisively, after which the route becomes a sequence of shorter rises and dips between tops. Around Giolabhal Glas, the ground broadens and the navigation becomes more important, especially if cloud drops. One route description notes that the summit itself lies slightly north of the walled trig point, which is worth knowing so hikers do not assume the first obvious structure is automatically the highest spot. (visitouterhebrides.co.uk)

The southern half of the horseshoe tends to be rockier underfoot and, in places, more pleasant to walk than the heather-clad northern side. By contrast, some of the descent lines and lower slopes can be awkward, with longer heather and wetter ground making progress slower than the map suggests. That means this is not a route to underestimate late in the day: even once the main summits are behind you, the return can still demand concentration and steady footwork. (walkhighlands.co.uk)
