Lumb Hole Falls is a waterfall situated on Crimsworth Dean Beck near Hebden Bridge in West Yorkshire. The falls tumble into a rocky gorge surrounded by woodland, making them a popular destination for walkers exploring the valley.

Reaching the base of the falls requires some effort — a bit of scrambling over rock slabs is needed to descend to the lower level.

The surrounding Crimsworth Dean valley offers scenic walking through woodland and open hillside, with the beck providing additional smaller cascades along the route.
