There are various mountains named Beinn Dearg in Scotland, but this one is the fourth highest of the Torridon mountains, with an elevation of 914 m (2,999 ft), meaning it just falls below the qualification for being listed as a Munro. Its prominence is around 469 m (1,538 ft).
It has all the typical characteristics of a Torridon hill, with its steep, craggy terraced sides scarred with deep, near vertical gullies. After some easy scrambling, there are good open views from the summit ridge, although because this mountain is not classed as a Munro, it is far less climbed than its neighbouring higher hills.
The usual starting point is the car park at the bottom of the Abhainn Coire Mhic Nobuil, which is also used for an ascent of Beinn Allligin.
