Venezuelas Tepuis

Venezuela’s Tepuis: What Arthur Conan Doyle Couldn’t Have Known

When Arthur Conan Doyle wrote The Lost World in 1912, he based it loosely on reports of Venezuela’s tepuis: ancient sandstone table mountains rising sheer from the jungle, their summits so isolated that they evolved separate ecosystems. He got the atmosphere right. What he couldn’t have anticipated is what they actually contain: an extraordinarily high proportion of endemic plant species (around 50% of summit flora exists nowhere else on earth), peculiar quartz landscapes called lajas, and, in the case of Auyán-tepui, Angel Falls.

The Basics

Tepuis are remnants of the Guiana Highlands, a geological formation that was once a continuous plateau. Erosion over hundreds of millions of years left the resistant sandstone caps standing alone. Most are in the Gran Sabana region of southeastern Venezuela, within Canaima National Park (UNESCO World Heritage since 1994).

Canaima National Park covers 30,000 square kilometres, making it one of the six largest national parks on earth. The core tourism area is around Canaima Lagoon and the flights to Angel Falls. The tepui trekking is a separate matter entirely.

The Current Situation

Venezuela’s political and economic situation as of 2026 makes independent travel complex. The infrastructure that existed pre-2015 has deteriorated significantly. Flights between cities are unreliable. The official exchange rate and black market rate differ substantially. This doesn’t mean the tepuis are inaccessible, but it means going with an established operator who handles in-country logistics is more important than for almost any other destination in South America.

Santa Elena de Uairén, near the Brazilian border, functions as the gateway for Gran Sabana access and has historically been easier to reach than Canaima from a logistics standpoint.

Angel Falls

At 979 metres (3,212 feet) free-fall height, Angel Falls is the world’s highest uninterrupted waterfall. It drops off the edge of Auyán-tepui. The falls are named after Jimmie Angel, an American aviator who crash-landed on the summit plateau in 1937 while searching for gold (he and his party walked out in 11 days).

Access is by light aircraft from Ciudad Bolívar or Canaima to a jungle airstrip, then by dugout boat along the Río Churún (around 3 hours depending on river level), then a trail through forest to viewpoints below the falls. The overflight version (plane only, no boat) gives you a view of the falls but not the experience of being near them.

The dry season (December-March) brings lower water levels and potentially reduced fall volume. The wet season (June-October) gives full flow. Both are worth seeing for different reasons.

Mount Roraima

Roraima is the most trekked tepui and the most geologically dramatic. The summit plateau (2,810 metres) is a landscape of quartzite rock formations, carnivorous plants, pink mist frogs (endemic to the summit), and, on the Venezuelan/Brazilian/Guyana triple border, a stone pillar marking where the three countries meet.

The standard trek starts in Paraitepuy village (reached by vehicle from Santa Elena) and takes 6 days return. The first 3 days are through savannah and forest; the final ascent to the summit is via a natural ramp on the Venezuelan side (the only feasible route on foot). Weather on the summit is cold and wet year-round; temperatures around 5-15°C and daily rain.

A licensed guide is legally required and genuinely necessary: the summit is a labyrinth and the trails are not marked.

Practical Planning

Fly into Ciudad Bolívar (from Caracas) or consider crossing from Brazil at Pacaraima (Santa Elena de Uairén is 14km north). Brazilian entry to Santa Elena is logistically simpler for many travellers given Caracas’ flight connections.

Budget $150-300 USD per day for guided trips including food and logistics. Cash in USD is the most practical currency. Carry more than you think you need.
