Di Gilbert works full time as an Independent Mountaineering Instructor, based in the Cairngorm National Park.

She has climbed the world's 7 summits and completed all 282 Munro's.

In 2005 Di successfully led her first expedition to the summit of Mount Everest. Having said she would never go back, she returned in 2019.

Di will be returning in 2020 for a third time to lead the Adventure Peaks North Ridge Expedition.
