Meall na Aighean forms part of the Glen Lyon Horseshoe or Carn Mairg Group. This is 4 Munros which form an arc round the Inverar Burn giving a long 18km circular route. Meall na Aighean is the last peak climbed when climbed in a clock-wise direction ( recommended) Meall na Aighean is a twin peaked summit, with the true summit lying to the NE only 7m higher.
Meall na Aighean is connected to neighbouring Munro Carn Mairg via a low col to the north.
The summit has a gentle SW ridge that leads back to Inverar to descend and complete the horseshoe. There is an eastern ridge that ends in an abrupt spur at the peak of Beinn Dearg (not a Munro) which is extremely craggy in all directions especially to the south and north. This is not normally attempted due to lack of energy after the 18km you will have walked so far round the horseshoe to this point!
The terrain is mostly grassy slopes with a few craggy outcrops near the summit. The hill on its own may not be regarded as one of the classics but including it with the horseshoe walk is a great expedition
