The first day of the trek to the summit of Mount Roraima — a flat-topped tepui rising from the Gran Sabana like a natural fortress, the landscape that inspired Arthur Conan Doyle's "The Lost World." Licensed guide required.

Stops on This Tour (8)

1. 1
   Savanna Crossing The trail crosses open savanna — the Gran Sabana, one of the oldest landscapes on Earth. These grasslands sit atop the Guiana Shield — Precambrian basement rock up to 3.6 billion years old. The flat-topped tepuis are erosional remnants of a vast sandstone plateau that once covered the entire region.
2. 2
   Tek River Crossing The first river crossing — the tea-coloured water is stained by tannins from the ancient sandstone. The rivers of the Gran Sabana are among the oldest drainage systems on Earth. Piranhas inhabit some of the larger rivers, though the Tek is generally safe for wading.
3. 3
   Roraima First View Mount Roraima appears ahead — a vertical-sided mesa rising 1,000 metres above the savanna. The flat summit is perpetually shrouded in cloud. The visual impact is extraordinary; the mountain looks artificial, as though placed on the landscape by design. Conan Doyle's description of a "Lost World" hidden on its summit was inspired by early explorer accounts.
4. 4
   Rio Kukenán Crossing The trail crosses the Kukenán River — glacial water from the neighbouring tepui of Kukenán. Kukenán's waterfall — Angel Falls's lesser-known cousin — is visible cascading from its summit cliff, the world's fifth-highest waterfall at 674 metres.
5. 5
   Kukenán Tepui Viewpoint Kukenán Tepui dominates the western skyline — its vertical walls streaked with waterfalls. The two tepuis — Roraima and Kukenán — stand like twin fortresses. The cliff faces are sandstone, deposited as sand in shallow seas 1.8 billion years ago and hardened into rock.
6. 6
   Savanna Camp Approach The trail crosses more savanna, with Roraima growing larger with every step. The grass here is scattered with carnivorous sundew plants — their sticky leaves trapping insects to supplement the nutrient-poor soil. The ecosystem has evolved in isolation for millions of years.
7. 7
   Base Camp Rio Tek The first camp sits beside the Rio Tek at the base of Roraima. The wall of the tepui rises directly above — a vertical cliff of sandstone. Tomorrow's route ascends the only feasible path, a natural ramp on the southwestern face. The guides prepare dinner over open fire.
8. 8
   Roraima Wall Viewpoint From camp, the cliff face is overwhelming — 400 metres of vertical sandstone, its surface etched with dark streaks of water seepage. The rock is layered: each stratum represents a different era of deposition, reading like a geological calendar spanning hundreds of millions of years.
