They also attempted to climb the nearby mountain they called Pyramid Peak (later renamed Spantik, as part of the Spantik-Sosbun Mountains). They camped the first night at and the second at . An ailing porter forced them to camp the third night at rather than and they eventually left him behind. They ascended a peak, giving Fanny a new altitude record. William and a porter climbed toward the needle-like spire that was the expedition's goal. However, he abandoned the summit attempt a few hundred feet from the top because he realized they could not have descended to a safe altitude before altitude sickness set in. After returning from their travels, the Workmans lectured all over Europe. Fanny lectured in English, German, or French, as the occasion required. At one talk in Lyon, France, 1000 people crowded into the auditorium and 700 were turned away. In 1905 Fanny became the second woman to address the Royal Geographical Society. (Isabella Bird Bishop had been the first in May 1897.) Her talk was mentioned in "The Times". The Workmans returned to Kashmir in 1906, and were the first Westerners to explore the Nun Kun massif. For this trip, the couple hired six Italian porters from the Alps, 200 local porters, and Savoye returned as guide. As Isserman, Weaver and Molenaar explain in their history of Himalayan mountaineering, the Workmans despised the local porters but were forced to recruit them; "their otherwise invaluable books read like one long, anguished harangue against the lazy, lying, thieving, mutinous cheats on whom they unhappily depended for local support". They planned a sequence of four camps from to . Despite labor problems, the Workmans spent the night higher than any previous mountaineers— on top of Z1 on Nun Kun—at what they called "Camp America". William wrote of Fanny:  The map the Workmans made during this trip was of low quality. According to Mason, the couple did not have a good sense of topographical direction, which meant that their measurements were inaccurate and unusable by the Survey of India. From , at the age of 47 in 1906, Workman climbed up to Pinnacle Peak () (which she believed to be ), a subsidiary peak in the Nun Kun massif of the western Himalaya. It was her greatest mountaineering achievement. As Isserman, Weaver and Molenaar point out, the fact that she "climbed the mountain at all, without benefit of modern equipment and encumbered by her voluminous skirts, speaks to both her ability and resolve".
