Beinn Teallach is the most westerly Munro in the Monadh Liath and is normally climbed in conjunction with Beinn a Chaorainn which is connected by a low bealach via Beinn Teallach's NE ridge. Beinn Teallach as not perhaps as exciting as its neighbour and takes on a more rounded shape but does possess some fine craggy cliffs on its eastern slopes. . The sides of Beinn Teallach are bitten into by several corries giving many summit ridges the best of these being to the NW and NE with steep craggy slopes on either side of them. The south ridge runs down over easy slopes taking you out at the A86 road at Roughburn this is the usual route of ascent for the Munro,
As mentioned Beinn Teallach is often climbed with Beinn a Chaorainn to the east. This can be achieved by following the NE ridge from Beinn Teallach and crossing over a low bealach to Beinn a Chaorainn. From this angle you can best appreciate the east face of Beinn Teallach, easily its best feature.
There is parking available at Roughburn off the A86. The entire walk if including Beinn a Chaorainn is around 13km.
