The standard ascent, always combined with Conival: up Gleann Dubh from Inchnadamph, a badly eroded climb beside the Allt a' Choinne Mhill and a quartzite rock staircase to the bealach below Conival, up its north ridge, then a very rough 1.5 km traverse over quartzite boulders and a stony arête to Ben More Assynt. Return the same way: 17.25 km, 1,077 m, 8.5–10 hours.

Park at the public car park in front of the Inchnadamph Hotel. Walk north over the River Traligill bridge on the A837 and turn right along the private road to Inchnadamph Lodge, past the hostel and through a gate, crossing the Allt Poll an Droighinn on a concrete bridge. Beyond the whitewashed cottage of Glenbain a good path continues up the glen past a plantation; at the fork keep left (right goes to the Traligill caves) along the north side of Gleann Dubh. After about 4.5 km the climb begins: a boggy stretch, then a badly eroded path up the north side of the Allt a' Choinne Mhill to a shallow grassy corrie. Cross the burn and climb the band of quartzite crags by a rocky staircase just right of the burn (a few cairns), reaching the upper corrie and the bealach between Conival and Beinn an Fhurain. A stony path climbs Conival's north ridge, with views into Coire a' Mhadaidh, to the wind-shelter cairn on Conival (987 m). Head east down crags and boulders, along a stony arête with some awkward moves on exposed slabs (care when wet) and up more scree over point 974 to the summit of Ben More Assynt (998 m), a shattered lump of quartzite. The ridge is slower going than it looks despite only about 100 m of re-ascent. Return the same way over Conival and down the glen.

Overview

The highest point of Sutherland (998 m), a remote quartzite-capped mountain hidden behind Conival in the east of Assynt. Always climbed with Conival from Inchnadamph on a very rough, rocky 8.5–10 hour day with a desolate, sweeping view.

Ben More Assynt (Beinn Mhòr Asainn, 'big mountain of Assynt') stands in the east of Assynt, apart from the area's famous isolated sandstone peaks such as Suilven, and is hidden from the A837 by its neighbour Conival. Its upper slopes are capped by pale quartzite boulders. It sits on Scotland's main watershed: the River Traligill drains west to the Atlantic, the Oykel and Cassley east to the Dornoch Firth. A 1 km ridge leads to its South Top (960 m).

The normal route from Inchnadamph climbs Gleann Dubh and Conival first, then crosses the 1.5 km quartzite ridge to Ben More Assynt and returns the same way: 17.25 km and 1,077 m of ascent, 8.5–10 hours. The going above the bealach is extremely rough, on boulders and scree, and the connecting arête has a few awkward moves on exposed slabs.

The mountain lies in the Moine Thrust Belt, a classic locality in the history of thrust tectonics, and more than 88 km² around it are a Site of Special Scientific Interest for geology, rare plants and freshwater habitats. The summit view is of a vast, bare wilderness in every direction.

Climbing Notes

Plan for a long day: 8.5–10 hours, much of it on sharp quartzite boulders that are slow and tiring underfoot. Good boots with ankle support, a map and compass, and the ability to navigate on featureless boulder ridges in mist are essential. The arête between Conival and Ben More Assynt needs care, especially when wet. The south ridge to the South Top and beyond is a more serious scramble far from any road and is rarely done. In winter the ridges are a serious mountaineering undertaking with short days. Inchnadamph has a hotel and a hostel at the start.

History

In April 1941 an Avro Anson crashed on the mountain, killing all six crew; because the site was so inaccessible they were buried there, under a cairn. In 2012 the Commonwealth War Graves Commission replaced the deteriorating cairn with a 600 kg granite marker at about 600 m, one of its most remote grave sites.
