Southern Black Cuillin

Sgurr nan Eag and Sgurr Dubh Mor

Scrambling route from Coir' a' Ghrunnda up Sgurr nan Eag and Sgurr Dubh Mor

From Glen Brittle, the route to Sgurr nan Eag and Sgurr Dub Mor at the southern end of the Black Cuillin gradually builds up the grade, culminating in the final ascent of Sgurr Dubh Mor - requiring a few moves up ledges to reach the summit.

Following on from Blaven, Bruach na Frithe and Sgurr na Banachdich, the two Munro peaks, Sgurr nan Eag and Sgurr Dub Mor at the southern end of the Black Cuillin offer the next level up of difficulty. The route to these peaks gradually increases in challenge, culminating in the final ascent of Sgurr Dubh Mor - requiring a few awkward moves over small slabs and a squeeze through a narrow gap (Grade 2 scramble) to then reach the summit crest.

This demanding route requires a good head for heights and experience in rock scrambling. The grippy gabbro rock aids climbing, but some sections are loose or polished, becoming slippery when wet. Additionally, the rock around Loch Coir' a' Ghrunnda is particularly abrasive.

For those seeking a longer challenge, the route can be extended to Sgurr Alasdair and the peaks surrounding Coire Lagan, though the difficulty increases significantly.

Standard OS maps can be unclear in this terrain - Harvey's Superwalker map and the SMC's Scrambles on Skye guidebook are highly recommended (see below). Alternatively, hiring a guide can enhance enjoyment and safety - The Highland Mountain Company offers experiences like a 2-day Cuillin Ridge Traverse, a 4-day Munro course or tailored experiences.

Route description


1. Getting to Glenbrittle

The Black Cuillin from Carbost

The Black Cuillin from Carbost

From Sligachan on the A87, take the A863 west towards Carbost. After a few miles, as you approach Loch Harport, turn off for Carbost. Just before entering the village, you'll reach a junction by a rough campsite - take the narrow road to the left signposted for 'Glen Brittle.'

This single-track road with passing places passes a large car park for the Fairy Pools and continues to the road-end by the entrance of Glenbrittle Campsite. If you're not staying at the campsite, roadside parking is available for around 25 vehicles by the entrance to the campsite, with additional space a few metres back up the road should this be full.


2. Coir' a' Ghrunnda

From the Glenbrittle campsite, walk through the site, past the toilets and wash facilities, and take a stile over a fence. Follow a path uphill to cross a track and continue eastwards aiming for the dark corries of the Black Cuillin.

After around 1km, the path comes to an obvious junction - turn right to drop down to cross a burn, then follow a well-constructed, if rather rough in places, path south-east for 1 km to cross the Allt Coire Lagan .

Shortly after crossing the burn, the path climbs a little and comes to a vague junction - take the left fork, keeping to a higher path which travels around the base of Sron na Ciche, then turns northwards to begin climbing into Coire Ghrunnda.

The path now quite rough, travels through a gap then rough ground and over bouldery terrain to reach the base of rock close to the tumbling waters of the Allt Coir' a' Ghrunnda. Keep tight to the rock-wall on your left and firm holds should be easily found to clamber up the rock ahead.

As ground levels, a straightforward walk then reaches the heart Coir' a' Ghrunnda - a magnificent place with the rock of Sgurr Alasdair and Sgurr Dubh Beag towering above Loch Coir' a' Ghrunnda below.

Cross the outflow from Loch Coir' a' Ghrunnda and follow the southern shore to its easternmost point, where a small inlet reveals a shimmering sandy bank beneath the water.

Ahead, a field of boulders and stones slopes upward beneath the dark rocks of Sgurr nan Eag's northern ridge. This is the easiest and most direct route to the Munro's summit.

Apart from some minor, straightforward scrambling, the ascent presents no real difficulties. Soon, the ridge crest is reached, and the ground levels out for a final, easy walk to the summit.

4. Sgurr Dubh an Da Bheinn

Retrace your steps along Sgurr nan Eag's northwestern shoulder, then begin descending as the crest curves northward. At some point, you'll need to leave the ascent route and stick to the crest - turning too early can lead to trickier terrain.

Further along, the route eases, becoming less technical, while the imposing bulk of Caisteal a' Garbh Choire dominates the view ahead. This massive block of rock is easily bypassed on the right (east), leading to a narrow, windswept bealach with a distinctive hole in the rock.

From here, a sustained but enjoyable section of easy scrambling climbs up Sgurr na da Bheinn's southern shoulder. Multiple route options present themselves on the way, but generally, staying slightly on the Coire Ghrunnda side of the crest provides the best line to the summit .

5. Sgurr Dubh Mor

Sgurr Dubh Mor from Sgurr an Da Bheinn

Sgurr Dubh Mor from Sgurr an Da Bheinn

Since Sgurr Dubh Mor lies east of the main ridge, most walkers opt for a there-and-back route - making this a good opportunity to leave rucksacks on the summit of Sgurr an Da Bheinn. However, be wary of the local ravens - they've mastered the art of opening rucksacks to steal food !

At first glance, the crest towards Sgurr Dubh Mor appears technical, but an easier alternative avoids most difficulties. Begin by heading east towards the top of the crest, then look for a vague path on loose scree to your left (north). Follow this as it twists below minor dark buttresses, gaining the ground beneath the col between Sgurr nan Da Bheinn and Sgurr Dubh Mor. From here, ascend a slope of shattered stone and boulders to the col .

An intimidating rocky buttress stands on the Sgurr Dubh Mor side of the col - pass under this and cross to the southern side of the col.

Follow a ledge around and below the buttress, then cross some grass before scrambling up some fine scree to reach another ledge. Follow the ledge eastwards for a few paces and climb a slab (which can be tricky when wet) to gain yet another ledge. A second short slab is then ascended, followed by another ledge, a left turn and a squeeze between a gap in rocks to a clamber up onto Sgurr Dubh Mor's airy crest.

6. Return and route to Sgurr Alasdair

Sgurr an Da Bheinn from Sgurr Dubh Mor

Sgurr an Da Bheinn from Sgurr Dubh Mor

From the summit of Sgurr Dubh Mor, carefully retrace your steps back to the col . You could return to Sgurr an Da Bheinn by descending the scree and passing beneath the dark buttresses. Alternatively, the more direct route up the ridge ahead looks more obvious from the col than that from the view earlier from Sgurr an Da Bheinn and does feel easier to ascend than descend, however is significantly more exposed than the path below the buttresses.

Once back on Sgurr nan Da Bheinn , you could descend back to the windy bealach via the same route used earlier, then drop directly to Loch Coir' a' Ghrunnda. A finer option would be to begin heading northwest along Sgurr nan Da Bheinn's crest, gradually losing height. There are no difficulties, but the route down may not be too obvious, requiring some trial and error with twists and turns, but once located, it provides an easy descent to the northern shore of Loch Coir' a' Ghrunnda.

From the north-western ridge of Sgurr nan Da Bheinn, the route can be extended towards Sgurr Alasdair. For competent scramblers a fine option is to traverse the top of scree slopes and pass beneath cliffs to reach a small cave, from where a rough scramble up Sgurr Alasdair's southwest shoulder leads to the summit (more details on this can be found on the Cuillin South page). Alternatively, for climbers, a direct route can be made to the top of the Great Stone Chute below Sgurr Alasdair via the infamous 'TD Gap'.

Other maps :



The Harvey Superwalker of the Cuillin is recommended, showing the ridge in detail at 1:25000, with the core of the ridge additionally at 1:10000. The SMC pocket guidebook to Skye Scrambles is also highly recommended to accompany the map. The OS Landranger map doesn't show enough detail and the OS Explorer map shows so much detail it's difficult to identify features !

The rock on Skye is magnetic in places and can therefore occasionally render a compass unreliable. Overhanging rock can also interfere with GPS signal.
