Sgurr Mhic Choinnich is a difficult climb as the walk will inevitably involve a large scree climb which is tiring to say the least. Although it is connected on its north ridge to Sgurr Dearg and by its south ridge to Sgurr Alasdair neither of these crossings are a particularly easy walk and is only really accessible by very confident scramblers or climbers. Hence the access is via Coire Laggan on the west side of the Cuillin ridge from Glen Brittle. The coire bites deep into the ridge with a steep back headwall covered in scree. This is a tiring climb until you reach the lowest point on the ridge. From here Sgurr Mhic Choinnich can be summated via its NW ridge but you are not out the woods yet and will require serious scrambling to reach the top.
Sgurr Mhic Choinnich is one of the classics of Scottish mountaineering and should definitely meet all your expectations. The views are as expected... fantastic in all directions particularly north to the east face of the Inaccessible Pinnacle and south to Sgurr Alasdair and "Great Stone Shoot". Enjoy!
