South American Tepuis

The sandstone that forms the tepuis of the Guiana Highlands is between 1.7 and 2 billion years old. For context, the first complex multicellular life on Earth appeared around 600 million years ago. The rock beneath your feet on the summit of Mount Roraima predates it by more than a billion years. These flat-topped mountains (the word tepui means “house of the gods” in the Pemon language of the Venezuelan indigenous people) were once part of a continuous sandstone plateau covering the region. Millennia of erosion removed the connecting material and left the mesas standing in isolation, which is why each summit functions as its own evolutionary island: species evolve separately on the plateau of one tepui and may not exist on any other, or anywhere else on Earth.

What Tepuis Actually Are

There are around 115 tepuis scattered across Venezuela, western Guyana, and northern Brazil. The tallest and most well-known is Mount Roraima, at approximately 2,810 metres. The largest by surface area is Auyantepui in Venezuela’s Canaima National Park, source of Angel Falls, the world’s highest uninterrupted waterfall at 979 metres. Roraima was the inspiration for Arthur Conan Doyle’s 1912 novel “The Lost World,” written after the author read reports from the first documented ascent in 1884. The geological isolation is real: the Roraima mouse, the tepui brushfinch, and various carnivorous plant species (sundews, pitcher plants) are found on tepui summits and nowhere else on Earth.

Mount Roraima

Roraima sits at the intersection of Venezuela, Brazil, and Guyana. The standard tourist trek approaches from the Venezuelan side, starting from the Pemon village of Paraitepuy. The hike takes five to eight days round trip: two to three days crossing open savanna to the base, one day ascending the ramp (the only non-technical route to the summit), and then time on the top before the return.

A guide is compulsory and is readily arranged through operators in the town of Santa Elena de Uairen, the nearest Venezuelan town of any size. The most practical access route from outside Venezuela currently runs via Boa Vista in northern Brazil: fly to Boa Vista (served from major Brazilian cities), take a bus or private transfer four to five hours to the Pacaraima border crossing, and continue into Santa Elena. Venezuela’s internal travel situation has been difficult for years; current conditions should be checked with a recent source before travel.

The best time for the trek is the dry season, December through April, when trails firm up and the summit is sometimes clear of the cloud that otherwise often envelopes it. The summit plateau is strange terrain: black quartz crystals, pink-tinged rock, endemic plants in the crevices, and pools of dark water. The weather can be brutal regardless of season; waterproofs are required.

Angel Falls and Canaima

Auyantepui, the largest tepui by surface area, is in Canaima National Park, a UNESCO World Heritage Site in Bolivar State, Venezuela. Angel Falls drops from the rim of Auyantepui 979 metres to the canyon below, its water turning to mist before it reaches the ground. American aviator Jimmie Angel, who crash-landed his plane on the summit in 1937 while searching for gold (and walked off the mountain), is the source of the English name; the Pemon name is Kerepakupai Merú.

Access to the falls is by small aircraft to the Canaima lagoon camp (roughly 50 minutes from Ciudad Bolivar or Santa Elena), then by motorised canoe along the Churun River to a point within hiking distance of the falls. The full return trip from the camp typically takes two days. The falls are most impressive in the rainy season (June through November), when water volume is highest; in the dry season the flow reduces considerably.

Canaima Camp, adjacent to the iconic pink-tinged lagoon with its small tepui backdrop waterfalls, is the main lodging option. It is operated by Grupo Cacique and can be booked through agencies in Ciudad Bolivar. Standards are basic but the location is exceptional.

Kaieteur Falls, Guyana

Kaieteur Falls in Guyana’s Potaro-Siparuni region is the world’s most powerful single-drop waterfall by water volume, falling 226 metres (the single-drop measurement differs from Angel Falls’ total height). The full descent, including a lower cascade, reaches 741 feet. Five times the volume of Niagara Falls goes over the edge; the spray is visible from the aircraft on approach.

Access from Georgetown is by small aircraft. Day tours depart from Ogle Airport and take roughly one hour each way, with two hours on the ground for the guided walk through the national park to the three main viewpoints. Tours run on Fridays, Saturdays, and Sundays and require a minimum of nine passengers to operate; the cost is around USD $300 per person including flights. Tours are weather-dependent and can be cancelled on short notice; build flexibility into your schedule. The poison dart frogs (Allobates femoralis) visible around the falls are one of the wildlife highlights.

Practical Considerations

The tepui region sits in one of the world’s most remote areas of habitation. Infrastructure is thin, political conditions in Venezuela have made some areas logistically difficult, and the distances involved in any itinerary are substantial. None of this should deter the organised traveller, but it does require more careful preparation than a typical tourist destination.

Guyana is English-speaking and has seen increased international interest since significant offshore oil production began in 2019. Georgetown is the logical base for Kaieteur and has a modest but improving range of hotels. Venezuela requires more advance planning, ideally with a local operator handling logistics.

The best single piece of advice for any tepui journey: hire a specialist tour operator based in the region rather than attempting to arrange logistics independently. The terrain, the political complexity in Venezuela, and the need for licensed guides all reward this approach.
