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 Sgùrr Alasdair and the peaks surrounding Coire Làgan, 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
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

Heading into Coir' a' Ghrunnda and looking over to Rum
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 1km to cross the Allt Coire Làgan
.
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 Sròn 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.

3. Sgùrr nan Eag

Route from Coir' a' Ghrunnda takes the bouldery ground slanting to the right
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 Sgùrr 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.

View south over Gars-bheinn from Sgùrr nan Eag
rests atop scattered boulders, offering stunning views south to Gars-bheinn and over the South of Sleat towards Knoydart and Morar.

4. Sgùrr an Dà Bheinn

Returning along Sgùrr nan Eag with view over Coir' a' Ghrunnda
Retrace your steps along Sgùrr 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.

5. Sgùrr Dubh Mòr

Sgùrr Dubh Mòr from Sgùrr an Da Bheinn
Since Sgùrr Dubh Mòr 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 Sgùrr an Dà 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 Sgùrr Dubh Mòr 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 Sgùrr an Dà Bheinn and Sgùrr Dubh Mòr. From here, ascend a slope of shattered stone and boulders to the col
.
An intimidating rocky buttress stands on the Sgùrr Dubh Mòr 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 Sgùrr Dubh Mòr's airy crest.

The final pull up Sgùrr Dubh Mòr
, where a small, precarious cairn marks the top.

6. Return and route to Sgùrr Alasdair

Sgùrr an Dà Bheinn from Sgùrr Dubh Mòr
From the summit of Sgùrr Dubh Mòr, carefully retrace your steps back to the col
. You could return to Sgùrr an Dà 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 Sgùrr an Dà Bheinn and does feel easier to ascend than descend, however is significantly more exposed than the path below the buttresses.
Once back on Sgùrr an Dà 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 Sgùrr 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.
