This section includes some of the highest and finest mountains in Scotland, most notably Ben Nevis, the highest of them all. In the south-west corner of the area, between Loch Leven and Glen Nevis, is the long ridge of the Mamores.
The ten Munros in this range include Binnein Mor and Sgurr a' Mhaim, both fine mountains with narrow crests, and all the peaks except two are linked by high ridges which makes the traverse of the Mamores a splendid expedition.
Opposite them, on the north side of Glen Nevis, Ben Nevis dominates not only the town of Fort William at its foot, but also its nearby high mountains - Carn Mor Dearg, Aonach Beag and Aonach Mor. Although these three are high by the standards of other Scottish mountains, they are very much in the shadow of their greater neighbour. To the east of the Aonachs another long ridge, the Grey Corries, includes three fine mountains - Sgurr Choinnich Mor, Stob Coire an Laoigh and Stob Choire Claurigh.
Continuing eastwards beyond the Lairig Leacach, Loch Treig is deeply enclosed between the steep flanks of Stob a' Choire Mheadhoin and Stob Coire Easain on its west and Stob Coire Sgriodain on its east. Other hills of lesser height and character in the area near Loch Ossian include Chno Dearg, Beinn na Lap, Carn Dearg and Sgor Gaibhre.
To the north-east of Loch Ossian, extending in a long continuous ridge towards Loch Pattack, there are four high mountains - Beinn Eibhinn, Aonach Beag, Geal-Charn and Carn Dearg - and to their north Beinn a' Chlachair is the highest of three hills above Loch Laggan.
Finally, at the eastern edge of this section, there is Ben Alder and its much smaller neighbour Beinn Bheoil on the west side of Loch Ericht. Ben Alder is a high and remote massif with an extensive summit plateau surrounded by steep corries, and it may well be described as the finest mountain between Ben Nevis and the Cairngorms.
