South American Tepuis: Mountains That Belong to a Different Era

Tepuis are tabletop mountains found across the Guiana Highlands of Venezuela, Guyana, and Brazil. Flat-topped, steep-sided, and geologically ancient, the sandstone formations date back roughly 1.7 billion years, making them among the oldest exposed rock surfaces on the planet. They rise hundreds of metres from surrounding savannah and forest on sheer cliffs that nothing climbs. The isolation of their summits has produced extraordinary endemic plant life: carnivorous species, orchids, and mosses found nowhere else on Earth. Sir Arthur Conan Doyle based The Lost World on them in 1912, which is either a selling point or a warning, depending on your expectations about plateau ecosystems.

Canaima National Park in southeastern Venezuela, a UNESCO World Heritage Site covering nearly 30,000 square kilometres, is the most accessible tepui destination. The landscape there is genuinely unlike anywhere else.

Canaima and Angel Falls

Canaima village is the gateway, reachable only by small plane from Ciudad Bolivar (about one hour) or Caracas (roughly two hours). No roads reach it. The village sits on the edge of a lagoon fed by multiple waterfalls, the water a distinctive reddish-brown from tannins leaching out of the vegetation.

From Canaima, tours reach Angel Falls (Salto Angel), at 979 metres the highest uninterrupted waterfall in the world, dropping off the summit of Auyan-tepui. The falls were first confirmed by the wider world when American pilot Jimmy Angel crash-landed on the summit plateau in 1937. The aerial view from a small plane over the tepui is extraordinary; the 3-day boat-and-hiking expedition to the base gives you the perspective from below. October is generally the sweet spot: the rainy season produces full water volume but can obscure the falls in mist; the dry season gives clearer views but a thinner cascade.

Tours are run by local operators and professional Pemon indigenous guides who have managed this route for decades. Canaima has maintained a safe reputation for visitors even during Venezuela’s most difficult periods; it’s remote enough to be insulated from urban instability. Check current travel advisories for Venezuela before booking, but the park itself has remained accessible.

Roraima

Mount Roraima, at the convergence of Venezuela, Brazil, and Guyana, is the tepui for serious trekkers. The 6-day ascent from Paraitepui village leads to a summit that is a genuinely alien landscape: black crystalline rock, pink sand, and carnivorous bromeliads under near-constant cloud cover. The summit of Roraima was the first place Sir Walter Raleigh recorded in 1595; the full ascent was only made in 1884. Permits are required and guides are mandatory. Arrange through operators in Santa Elena de Uairen, the nearest town with facilities.

Kaieteur Falls, Guyana

Kaieteur Falls in Guyana is harder to reach than Angel Falls and consequently much less visited. The Potaro River drops 226 metres over a sandstone cliff at a volume per unit width that makes it one of the most powerful waterfalls on the planet by that measure. Day-trip flights from Georgetown are the practical approach (roughly $150-200 USD). Up close, the falls are more impressive than photographs suggest: the scale takes a moment to register.

What to Pack

Waterproof everything, sturdy hiking boots, strong insect repellent for the forest sections, and layers for summit temperatures that drop unexpectedly even at equatorial latitudes. If you’re trekking Roraima, you’re carrying your own gear for six days and every unnecessary kilo will be felt by day three.
