Auyán-tepui (Spanish pronunciation: [awˈʝan teˈpuj]), also spelled Ayan,[3] is a tepui in Bolívar state, Venezuela.

[1] It is incised from the north by a vast valley, the Cañón del Diablo (Devil's Canyon), formed by the Churún River.

The larger western portion of the plateau is partially forested, whereas the eastern part comprises mostly bare rock with only patchy vegetation cover.

Attempting to land on the heart-shaped mesa in 1937, Angel crashed his small Flamingo plane on top of Auyán-tepui and was forced to hike down the gradually sloping backside, a trip that took him and his crew 11 days to complete; he was immortalised when the waterfall was named after him.

[7] Around 25 species of amphibians and reptiles are known from the summit plateau of Auyán-tepui,[9][10] as well as numerous birds.
