Carn Mor Dearg is connected to Ben Nevis's north face via a long extremely impressive arÍte. This is the best way to climb Ben Nevis without getting into any forms of rock climbing. Carn Mor Dearg is a large Munro in its own right (4003ft) but sitting next to the Ben it feels dwarfed. The summit of Carn Mor Dearg sits at the highest point of a long North to South running ridge. There are extremely steep slopes to the west and east. There is a subsidiary peak north of Carn Mor Dearg called Carn Dearg Meadhonach.
Carn Mor Dearg is normally climbed from the west by climbing the first half of Ben Nevis via the tourist path before skirting round the western flanks of the hill to Coire Leis. It is a steep and unrelenting climb to reach any point on the summit ridge of Carn Mor Dearg. There is also a low col east of the summit to connect to Aonach Mor and Aonach Beag to make a fantastic multi day expedition with a high overnight camp or bivvy.
Carn Mor Dearg and more importantly the CMD arÍte is widely regarded as one of the best walks in Scotland and if you have a head for heights it will most definetely be a memorable day on the hills
