What is the name of the 98-metre underground waterfall in Yorkshire’s Gaping Gill cave?

Gaping Gill waterfall is the 98-metre underground waterfall inside Yorkshire’s Gaping Gill cave system.

Gaping Gill is a large limestone cavern on Ingleborough in the Yorkshire Dales. Fell Beck flows into the cavern through a shaft, creating one of Britain’s highest unbroken waterfalls. The water disappears into the cave and continues through an underground drainage system.

The main shaft is approximately 110 metres deep, while the waterfall itself is commonly described as about 98 metres high. This distinction matters: the cave opening, shaft depth, and free-falling water are related measurements but are not identical.

The cavern is not a conventional open-air tourist waterfall. Access involves specialist caving equipment, and organized descents have historically been arranged by local caving clubs. The surrounding Yorkshire Dales landscape is developed in Carboniferous limestone, a rock type that readily forms caves, shafts, and underground streams.
