Ben More Assynt is situated on a ridge of high ground which runs roughly north to south on the east side of the A837 road near Inchnadamph.

[3] An ascent of Ben More Assynt is usually combined with the neighbouring Munro of Conival, which if starting from the hamlet of Inchnadamph (grid reference NC250218), is climbed first.

Ben More Assynt’s summit lies 1.5 km (1 mi) east and is a demanding walk over quartzite stones and scree, even though there is only just over 100 metres of re-ascent.

The sharp arête is quite tricky to negotiate in places; according to Ralph Storer, it "has been flatteringly compared to the Aonach Eagach, with several unexpectedly awkward moves across exposed slabs requiring care (especially when wet)".

Protesters used Ben More Assynt in their arguments against the project, saying that the wind farm would have a detrimental effect on the view from the mountain and the sense of wilderness would be greatly reduced.

In April 1941, during the Second World War, all 6 of the crew on board an Avro Anson were killed when the aircraft crashed on Ben More Assynt.

In 2012, the Commonwealth War Graves Commission decided to replace the existing cairn, which had deteriorated in the harsh climate, with a 600-kilogramme granite marker to identify and protect the burial site.
