There are landscapes so improbable they seem to belong to another planet. Mount Roraima is one of them.
This flat-topped mountain, its vertical walls rising nearly 3,300 feet from the surrounding plain, towers over Venezuela’s Gran Sabana as if a giant blade had sliced a block of land away from everything around it.
It has anchored Indigenous mythology for centuries, inspired one of the most celebrated adventure novels of the 20th century, and quietly shaped one of the most beloved animated films of the 21st. None of that is an accident.
What Tepuis Are and Why They Matter
Roraima belongs to a family of geological formations found almost nowhere else on Earth: tepuis, flat-topped sandstone mesas with near-vertical walls. They sit atop the Guiana Shield, one of the oldest exposed sections of the planet’s crust, estimated to be 1.6 to 1.7 billion years old.
More than 85 percent of known tepuis lie in Venezuela, and Roraima is among the tallest. Its summit rises more than 9,200 feet above sea level, and the plateau itself spans roughly 12 square miles, straddling the borders of Venezuela, Brazil, and Guyana — one of the few places in the world where three countries meet on a mountaintop.
Tepuis began as vast sedimentary deposits that were slowly pushed upward over millions of years while erosion stripped away the softer terrain below, leaving these rocky islands suspended high above the savanna and jungle that surround them.
The result is an ecosystem almost entirely isolated from the rest of the continent.
The summit is home to plants found nowhere else. The plateau also features the Valley of Crystals, a field strewn with quartz, and “The Hotels,” a cluster of natural rock overhangs where trekkers shelter at night.
The Origin of the ‘Lost World’
For the Pemon people, who have inhabited this region for generations, Roraima is not simply a mountain.
In their mythology, it is the stump of an enormous tree that once held every fruit and plant in the world. The god Makunaima felled it, and the tree’s fall gave rise to the tepui and to the rivers of the region. The name Roraima is generally translated as “great blue-green,” while tepui is the Pemon word for “house of the gods.”
In the early 20th century, that same mystique captured the imagination of the Scottish writer Arthur Conan Doyle, who drew on it for his 1912 novel The Lost World — a story set on an isolated plateau where dinosaurs and prehistoric plants had somehow survived into the modern age.
Roraima’s enduring nickname, “the Lost World,” comes straight from that novel.
The Mountain Behind a Pixar Film
Nearly a century later, Roraima inspired another story, this one far better known to modern audiences: Pixar’s Up (2009).
To bring Paradise Falls to life — the legendary destination that lures elderly Carl Fredricksen across the sky — director Pete Docter and a small creative team traveled to Venezuela and climbed to Roraima’s summit as part of their field research, returning with thousands of photographs, videos, and sketches.
But the waterfall that appears in the film was not drawn from Roraima itself. It was inspired by Angel Falls, the world’s tallest waterfall, which plunges from Auyantepuy, another tepui in Canaima National Park.
Many accounts gloss over this distinction, but it’s worth making. Roraima gave the Pixar team the experience of walking on a real tepui. The waterfall the world remembers from the film belongs to another one entirely.
How to Visit Roraima Today
Unlike most hiking destinations, Roraima cannot be climbed independently.
The only route open to visitors starts on the Venezuelan side, in the Pemon village of Paraitepuy, roughly 56 miles from Santa Elena de Uairen, the town that serves as the staging point for treks.
National park regulations require hiring authorized local guides, typically arranged through agencies based in Santa Elena, which handle permits and transportation and provide support throughout the trek.
The full trek usually takes six to eight days and covers 43 to 56 miles round trip, depending on the route. The itinerary breaks down into roughly three days of ascent, one or two days exploring the summit, and two or three days back down.
It’s rated moderate rather than extreme, but it requires good fitness: you’ll hike for several hours a day, and the final climb to the plateau is steep.
Camping is rustic — no electricity, no hot water — so you’ll need proper mountain gear to be self-sufficient for several days.
The most practical route from outside Venezuela is to fly into Boa Vista, Brazil, and continue overland across the border, though infrequent domestic flights within Venezuela are another option.
The trek can be done year-round, but conditions on the summit are unpredictable in any season — fog, rain, and cold are common even during the dry months. Warm layers and waterproof gear are non-negotiable regardless of when you go.
A Plateau That Still Feels Like Another World
Strip away the Pemon myths, Conan Doyle’s fiction, and Pixar’s research trip, and Mount Roraima needs no embellishment: a mountain more than 1.6 billion years old, rising from an open savanna and sheltering an ecosystem that evolved in near-total isolation.
Reaching its summit remains one of the few chances left to stand in a place that truly lives up to the idea of a lost world that so many stories have tried to conjure.
