 The route then goes north up Glen Derry for before ascending the south-western flanks of Beinn Bhreac.From the bealach between Meall an Lundain and Beinn Bhreac it is a steep climb to the summit.An approach from the Aviemore side of the Cairngorms is feasible, starting at the Cairn Gorm ski centre, but this involves crossing or bypassing Cairn Gorm, Loch Avon, Beinn Mheadhoin and Beinn a' Chaorainn before reaching the mountain and is a long, hard walk.
