In 1928 he went to Kenya as a coffee grower and first climbed Nelion, a peak of Mount Kenya, in 1929. It was also in Kenya's community of Europeans where he met his future climbing partners Bill Tilman and Percy Wyn-Harris. Together with Wyn-Harris, he climbed the twin peaks of Mount Kenya. With Frank Smythe, Shipton was amongst the first climbers to stand on the summit of Kamet, 7756 metres, in 1931, the highest peak climbed at that time. Shipton was involved with most of the Mount Everest expeditions during the 1930s and later, including Hugh Ruttledge's 1933 Mount Everest expedition and the follow-up in 1936, the 1935 Mount Everest expedition which was Shipton's first as leader and the first for Tenzing Norgay, and the pioneering 1951 Mount Everest expedition which chalked out the now famous route over the Khumbu Glacier. Shipton and Tilman also discovered the access route to the Nanda Devi sanctuary through the Rishi Ganga gorge in 1934. Their shoe-string budget expedition operated in the Kumaon-Garhwal mountains continuously from pre-monsoon to post-monsoon, and set a record for single-expedition achievement that has never been equalled.
