Ben Macdui is the second highest Munro pipped to the top by Ben Nevis and 114ft. What it loses in height, Ben Macdui more than makes up for in bulk. When combined with its neighbouring peaks of Derry Cairngorm and Carn a Mhaim, this forms undoubtedly one of Scotlandís highest and best plateaus. The mountain separates two great passes, Lairig Ghru and the Lairig an Laoigh, which both make for great low level walks. The summit is surrounded by steep slopes with a lot of crags on the south east face overlooking Derry Cairngorm. A long ridge runs south to connecting Munro Carn a Mhaim. This is a common access route to Ben Macdui. Care must be taken to avoid the steep crags on either side of this ridge. A large plateau connects NW ringing round Loch Avon to Cairn Gorm, again this is a common access route. Derry cairngorm is connected to a high col on the NE ridge of Ben Macdui
The round of Ben Macdui and its neighbours Carn a Mhaim and Derry Cairngorm is one of the classics of Scottish mountaineering and is probably best to leave them for a clear day to get the best sense of just how vast these Munros are. You will definitely thank yourself.
