Meall Garbh forms part of a group of 4 Munros known as the Carn Mairg Group. This is an 18km circular route around the Inverar Burn in the North of Glen Lyon. The summit is twin peaked, with the NW summit being just a tad higher thus the true summit. The hill is rounded with little in the way of crags although the summit is rather rocky. There should not be any technical difficulties with this Munro. The Munro is easily accessible in all directions via long gently sloping faces. The north face has paths leading down to Kinloch Rannoch. The south slopes wind down moderately to Glen Lyon.
There are two main summit ridges that are used. The SW ridge leads via a subsidiary peak An Sgorr before leading to the Munro Carn Gorm the first in the horseshoe. The long E ridge leads across the head of the Inverar Burn to the reach the highest Munro in the group, Carn Mairg.
Meall Garbh on its own is not normally noted as being an exceptional Munro but by including in the above mentioned circular route taking in 4 Munros it makes a fine expedition.
