Creag Mhor, meaning Big Rock, is a Scottish Corbett, a mountain between 2500 and 3000 feet, and one of the few Corbetts in the Cairngorms.
The mountain is extremely remote, lying just north-east of the centre of the range, and is over 7 miles from the nearest motorable road. One of the few hill passes in the Cairngorms, the Lairig an Laoigh, which runs from Speyside southwards to Deeside, passes the the mountain less than a mile to its west along a valley that seperates it from its larger neighbour, Bynack More.
The mountain is relatively level on its upper reaches, and like most in the eastern Cairngorms, is dotted with granite outcrops, one of which, the largest, forms the summit and makes the mountain distinctive.
STEEPNESS: The Lairig an Laoigh path climbs gradually over the eastern shoulder of Bynack More to a height of nearly 800 metres and despite dropping down over 100 metres from then on, it leaves a straightforward climb up to the summit which is only particularly steep in the lower reaches before easing towards the summit tor.
TERRAIN: The well constructed path makes for quick progress from Glen More. It becomes more rutted and muddy in places as it descends over the shoulder with a couple of awkward crosses of streams. Once off the path the route up the mountain is of short heather with a few boggy places, but once higher up the vegetation becomes sparse and the going is quickened.
ACCESSIBILITY: The mountain is a long way from any habitation. The end of the public road from Glen More is around seven miles away but this is the quickest route to and from the mountain. The southern route from the Linn of Dee through Glen Derry is possible but much longer. The Cairngorm ski-centre road end is closest to the mountain but the route from here is mostly pathless and requires a lot of ascending and descending.
NAVIGATION: The path makes navigation easier in the early stages of the journey, keep left at a fork when climbing as the right fork heads up Bynack More. When reaching tiny Lochan a' Bhainne, leave the path and bear directly east up the hillside to the summit tor. It is easiest to descend the same way, any descent other than westwards leads into some of the remotest country in the Grampian Mountains, with no public roads or habitation for many miles.
DANGER: Only the length and remoteness of the journey. The summit tor is easily ascended by following the numerous grassy rakes with care.
