Beinn a' Chaorainn (Glen Spean)

Beinn a’ Chaorainn reaches a height of 1052 metres (3451 feet) and qualifies as both a Munro and a Marilyn. It stands in a section of the Grampian Mountains often known as the Loch Laggan Hills these include the Creag Meagaidh range five km to the NE and the adjoining Munro of Beinn Teallach which is just over two km to the west. Beinn a’ Chaorainn is usually climbed in conjunction with Beinn Teallach in a 13 km horseshoe walk around the Allt a’ Chaorainn, starting at Roughburn on the A86 road. The mountains name translates from the Gaelic language as “Mountain of the Rowan Tree”.[3]

Beinn a’ Chaorainn is basically a north-south orientated ridge which looks quite an undistinguished bulk when viewed from Roughburn (see picture), the best view of the mountain being from the east where the crags of Coire na h-Uamha give the mountain some character. This corrie’s name translates as the Corrie of the Cave although no significant cave is known in its environs although there are several small lochans within its higher recesses. It is drained by the Allt na h-Uamha whose glen separates the mountain from Creag Meagaidh massif to the east. Part of these eastern flanks of the mountain are clothed in coniferous woodland below the 550 metre contour. Coire na h-Uamha is split into two distinctive parts by an eastern ridge which gives a feasible route of ascent from the foot of the coire directly to the main summit, however some care is needed and in Winter conditions it is ranked as a Grade I route.[4][5]

Coire Buidhe (Yellow Coire) stands at the northern end of the mountain, this corrie is drained by the Burn of Algie, part of the headwaters of the River Roy. Two routes down the ridges on either side of this corrie connects to the adjoining Munros. One route goes NW and links to Beinn Teallach at a col with a height of 614 metres. The other route goes NE down to the Bealach a’ Bharnish (824 metres) before ascending onto the Creag Meagaidh plateau. The southern flank of the mountain descends to Glen Spean with more coniferous plantations below 400 metres while the western flanks are very steep as they fall to the glen of the Allt a’ Chaorainn. All drainage from the mountain finds its way to the west coast of Scotland via the River Spean, going either south directly to Glen Spean or north and going via Glen Roy before joining the Spean at Roybridge.[6]

The most popular route of ascent starts at Roughburn on the A86 at grid reference NN377813, there is parking at the Loch Laggan Dam, 700 metres to the SW. Forest roads and fire breaks take the walker through the forest to emerge onto the open hillside at a height of 400 metres. The route then goes NE up a broad ridge on the west side of the shallow Coire Clachaig. The view from the summit gives an excellent perspective of the Munros around Loch Treig.[8]
