Getting there & Parking
From Sligachan, the drive to Glenbrittle takes about 30 minutes. Follow the A863 before turning onto the winding Glenbrittle road.
Although the road has been resurfaced in 2024, it is still very narrow. During peak months the narrowness of the road can cause a significant amount of gridlock and tailbacks, so I would advise travelling early or late to avoid getting stuck.
Limited free parking is available outside Glen Brittle Youth Hostel; there is space on the left hand side of the road both before and after the bridge.
The route
The route begins by following a well-built path on the right-hand side of the river. It will gradually climb up past a series of beautiful waterfalls and pools.
Along the way, several paths branch off to the right, but stick to the main trail that follows the stream. After about two kilometres, the well-maintained section of the path comes to an end, giving way to a more worn and eroded route. Shortly after, the trail crosses the stream by a natural waterslide.
The path will level off slightly before re-joining the stream and branching left. It gets steeper again here but isn’t technical. After 3km you will cross the stream again and the gradient will begin to ease. Here the scree chute Coire An Dorus will come into view.
An Dorus ‘The Door’
After 3.8km the steep scree slope of An Dorus will begin. It’s a bastard, gaining around 280m of elevation in 500m. The gully narrows part way up, and then narrows even more a short distance from the top. The last 20m consists of sold rock and requires scrambling.
You’ll emerge into the door, which looks directly down to Loch Coruisk.
Exiting the door to the left requires a short tricky scramble, but once done the exposure and technically eases. From here it’s a short and steep 150m scramble up and around to the first munro.

Sgùrr a Mhadaidh
Sgùrr a Mhadaidh, which translates to "Peak of the Fox" in Gaelic, is one of the central peaks of the Cuillin Ridge on the Isle of Skye. Standing at 918 meters (3,011 feet), it offers a commanding position with views of the rugged Cuillin mountains, Loch Coruisk, Glenbrittle, and the surrounding sea.
Route to Sgùrr a Ghreadaidh
Enjoy the epic views before carefully retracing your steps back down to An Doras. You will have short, steep and awkward scramble to exit the other side of the Door and get onto the ridge.
Once this is cleared the scrambling is relatively straightforward and much less technical and exposed.
The scramble up and out of the door towards Sgùrr a Ghreadaidh
Follow the sloping ridge for 300m up to the second munro. The striking chasm of the Eag Dubh is navigated with relative ease by descending slightly to the left. The next challenge is a prominent rock feature known as the Wart, which can be bypassed to the right over slabby rocks. Beyond this point, the summit is reached shortly afterward.
Sgùrr a Ghreadaidh
Sgùrr a Ghreadaidh, meaning "Peak of the Torrent" in Gaelic, is the highest peak in the northern section of the Cuillin Ridge, standing at 973 meters (3,192 feet).
From the summit of Sgùrr a Ghreadaidh, the views are some of the most dramatic on the Isle of Skye. To the south, the Cuillin Ridge stretches like a sawblade, with Sgùrr na Banachdich and Sgùrr Dearg visible among its peaks.
To the west, the Glenbrittle valley and Loch Brittle unfold, with the shimmering waters of the Atlantic Ocean beyond. On a clear day, you can see across to the Outer Hebrides and the mainland peaks in the distance.
Looking north and east, the jagged contours of the Cuillin Ridge dominate the skyline, offering an incredible sense of the ridge's scale and beauty.
The section of ridge which continues to the slightly lower south peak is perhaps the narrowest arête in the whole of the British Isles, and is very exposed.
Ridge to Sgùrr na Banachdich
Only extremely experienced and competent scramblers should attempt to continue along the ridge. This route is highly committing, with no viable descent options until reaching Sgùrr na Banachdich, this route involves a km of continuous grade three scrambling which is very technical and incredibly exposed.
Only attempt this if you have the skillet, weather and equipment to do so.
You’ll initially continue up across the multiple tops of Sgùrr a Ghreadaidh. This will start with some down climbing down to the north side of the ridge. You’ll then scramble re-ascend up onto a very narrow section of ridge before descending north east down down towards the bealach.
The initial section up on Sgùrr a Ghreadaidh is incredibly narrow and exposed with very little bail out options. However once you begin descending the ridge, there are plenty of lower paths which sit beneath the main ridge.
After a thrilling descent down to a saddle, you then skirt to the right (north) hand side of a large rock before ascending the gradual slope up to Sgùrr Thormaid.
This is a steep and technical slab of rock. Although climbing it is relatively easy, it is the descent that is steep tricky. When looking down it towards Sgùrr na Banachdich I stuck to the left hand side of the rock when descending. This was apparently a lot easier than descending down the middle and right hand side (which the rest of the group did).
Once Sgùrr Thormaid is navigated. its just a steep scramble up to the third and final munro. Although not technical or exposed, it does have lots of loose rock and scree so take care if climbing in a group.

Sgùrr na Banachdich
The mid-point of the Cuillin Ridge, Sgùrr na Banachdich (965m) offers unbelievable 360 degree panoramic views over the west coast of Scotland.
Alongside seeing the entirety of the Isle of Skye and the Cuillin ridge, you will had endless views out over the Small Isles, and Outer Hebrides. The highlight has to be with the views along the ridge towards the Inaccessible Pinnacle and Sgùrr Alasdair, alongside down over Loch Coruisk.
The descent back down to Glenbrittle campssite is is not technical or exposed but is very steep, with the steepest sections consisting of very loose scree.
Final thoughts
As epic as the Cuillin Ridge is, it’s a dangerous and difficult route which I would only recommend hiking if you have the skillset, knowledge and weather window to do so.
The hike is extremely technical and exposed, so shouldn’t be taken lightly. If in doubt, give it a miss or hire a guide.
That being said this is one of the best and most impressive routes I have ever done, it’s extremely thrilling and offers some jaw dropping views. So, make sure you do it on a good day to fully enjoy it.
