Large solution caves in Silurian limestone are known throughout North Greenland with the earliest documented observations dating to the 1950s. In 1958, one large cave situated in Wulff Land was photographed during aerial reconnaissance. The image was sent to the University of Bristol and then eventually to members of the University of Bristol Spelæological Society (UBSS) where it set off a chain of events over decades that included many UBSS members, unimaginable research efforts, logistics planning and crucially, fundraising. This article presents the narrative of UBSS attempts to reach, enter and explore ’the big cave in Wulff Land‘, now known as ‘WUL-8’, which was finally achieved by a small team on 22nd July, 2023. Exploratory methods, observations, and the interdisciplinary research that was conducted during the 2023 expedition is presented.
