South American Tepuis: Mountains That Belong to Another World

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), they rise hundreds of metres from the surrounding savannah and forest. The isolation of their summits has produced remarkable endemic plant life — carnivorous species, orchids, and mosses found nowhere else on Earth. Sir Arthur Conan Doyle based The Lost World on them, which is either a selling point or a warning, depending on your outlook.

Canaima National Park, Venezuela

The most accessible tepui destination is Canaima National Park, a UNESCO World Heritage Site in southeastern Venezuela covering nearly 30,000 sq km. The gateway is Canaima village, reachable by small plane from Ciudad Bolívar (about 1 hour) or Caracas (roughly 2 hours). There are no roads in.

From Canaima, tours go to Angel Falls (Salto Ángel) — at 979 metres the highest uninterrupted waterfall in the world, dropping off the summit of Auyán-tepui. The falls are best seen by small plane (the aerial view is extraordinary) and by a 3-day boat-and-hiking expedition to the base. The rainy season (June-November) produces the greatest water volume but can obscure the falls in mist; the dry season gives clearer views but a thinner cascade. October is the usual sweet spot.

Roraima is the tepui that tends to attract the hikers. At the convergence of Venezuela, Brazil, and Guyana, it requires a 6-day trek from Paraitepui village. The summit is a bizarre landscape of black crystalline rock, pink sand, and carnivorous bromeliads under near-constant cloud cover. Permits are required and guides are mandatory — arrange through operators in Santa Elena de Uairén, the nearest town.

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. Day-trip flights from Georgetown are the easiest option (roughly $150-200 USD). The falls are dramatically more impressive up close than photographs suggest.

Practical Realities

Venezuela’s political and economic situation has fluctuated significantly in recent years and continues to affect infrastructure, currency exchange, and safety. Check current advice carefully before booking. Many tour operators working in Canaima are run by the indigenous Pemon people, who have deep knowledge of the area and whose economic participation is worth supporting directly.

What to Pack

The tepui environment calls for waterproof everything, sturdy hiking boots, strong insect repellent (particularly for the forest sections), and layers for summit temperatures that can drop unexpectedly. Don’t take more than you can carry — if you’re trekking Roraima, you’re carrying your own gear for 6 days.
