Cachoeira da Fumaça, Vertical waterfall in Chapada Diamantina National Park, Brazil.

Cachoeira da Fumaça is a waterfall in Chapada Diamantina National Park that drops vertically about 340 meters from high cliff faces above the surrounding landscape. The water descends as a thin ribbon and creates a misty effect in the air as it falls.

Local people knew the waterfall, but the wider public learned of it after bush pilot George Glass noticed it in 1960. It was long believed to be Brazil's highest until the 353-metre Cachoeira do El Dorado was discovered in Amazonas.

The name "Smoke Falls" comes from the wind spraying the thin flow into mist before it lands; locals also call it "Glass Falls". Visits are controlled by the Vale do Capão Guides Association (ACVVC), and the falls appeared in the 2006 film Dhoom 2, where Aishwarya Rai's character jumps from the cliff.

A hiking trail of about 6 kilometers from Vale do Capão reaches the viewpoint and demands moderate fitness level and proper outdoor gear. The path is well-used but some sections can become slippery, especially after rain.

During windy conditions the falling water breaks apart into droplets and never reaches the ground, instead evaporating into the air. This natural occurrence is what inspired the falls to be named after smoke or mist.
