Carn Eige or Carn Eighe as it is often spelt is a large Munro sitting in the rough grounds between Loch Affric in the south to Loch Mullardoch in the north. It sits near the end of a long curved ridge encasing Gleann a Choilich to the west. Carn Eige has three main summit ridges running N, E and S all connecting to adjoining Munros. The N ridge leads to Beinn Fhionnlaidh via Bealach Beag. The south ridge joins up with Mam Sodhail which is almost identical in appearance and stature to Carn Eige. A long knobbly eastern ridge runs for around 5km to Toll Creagach and Tom a Choinich but these are best left for a separate day. All ridges have steep drops and several crags but as long as you’re sensible should pose no technical difficulty.
Carn Eige's NE and SE faces are bitten into by large corries giving the summit a well defined shape and the walk from Mam Sodhail round the rim of Loch Uaine is a fantastic traverse.
As mentioned Carn Eige is best climbed in conjunction with Mam Sodhail and you may as well grab Beinn Fhionnlaidh further north while you’re up there as there is no other easy way of climbing it apart from Carn Eige. These are all remote Munros and will demand a long walk in but it will be worth it. The public road at the head of Loch Affric to the east makes the most logical starting point but other routes do exist from the west and south should you wish to take in other Munros in a multiday expedition.
