Ben Macdui

Ben Macdui sits right in central Cairngorms. It's height and distance from any reasonable starting point makes completing Ben Macdui a long day out whichever way you do it. It is either possible to start/finish at Derry Lodge to the South-East and combine it with Derry Cairngorm and Carn a'Mhaim. But there is also high plateau joining it to Cairngorm mountain to the North, there isn't really an easy way to make this in to a circular route though, so you would have to realistically do it as an out and back.
