Tepui

Tepui are massive sandstone plateaus that tower above the rainforest with sheer vertical walls, some reaching over ten thousand feet in height. The flat summits remain isolated by cliffs that drop straight down on all sides, creating natural fortresses in the clouds.

These mountains formed roughly two billion years ago from sandstone layers that later eroded into separate peaks. European explorers began documenting them in the late nineteenth century, with the first recorded ascent of Mount Roraima taking place in 1884.

The Pemon indigenous people name these mountains tepui, meaning house of the gods, considering them sacred places within their ancestral territories.

Visiting requires permits from national park authorities, with most travelers joining guided treks or booking helicopter flights during the dry season. The summits often disappear into clouds, so visibility can change quickly even when conditions seem clear.

The summits shelter plant and animal species found nowhere else on Earth, having evolved in isolation for millions of years. Some frogs and insects live only on a single mountain and were discovered within recent decades.
