Northernmost Point of Brazil
Brazil's northernmost point sits atop Monte Caburaí, a Precambrian plateau rising 1,465 meters above sea level on the Guyana border in Roraima state. An iron border pole marks the exact spot at 5°16′20″N, 60°12′43″W. You won't find crowds here — the summit only opened to non-military visitors in 2005, and reaching it means a grueling five-day trek through dense rainforest. There's far more to uncover about this remote and fascinating landmark.

Where Exactly Is Monte Caburaí, Brazil's Northernmost Point?
Monte Caburaí sits directly on the Brazil-Guyana border in Roraima state, marking the country's northernmost point at the headwaters of the Ailã River, also called the Uailã River, which originates at the mountain's 1,465-meter summit.
This border marker defines where Brazil's northern frontier meets Guyana, forming part of the international boundary delineation.
You'll find the location within Mount Roraima National Park, a protected area sitting atop a Precambrian shield roughly 600 million years old.
The park's highland plateau reaches 1,000 meters, surrounded by dense tropical rainforest, canyons, and waterfalls.
Reaching this extremity means traversing indigenous pathways through marshlands and river crossings under harsh weather conditions.
The river source itself confirms the site's status as Brazil's absolute northern extremity. Monte Caburaí is officially recognized as one of Brazil's extreme points, helping define the full geographic scope of the country's boundaries.
Much like how the Democratic Republic of the Congo's colonial-era boundary negotiations resulted in a narrow coastal corridor that altered its geographic classification, Brazil's precise borders were also shaped by historical boundary agreements that determined its ultimate territorial extent.

You'll find the summit accessible via the 5.6 km border marker, connecting Brazil's highland shield to the broader Pakaraima Mountains range. Geographic data about Monte Caburaí has been documented and maintained by IBGE, Brazil's official statistical and geographic authority.
The region surrounding Monte Caburaí is home to the Ingarikó native people, who inhabit the Raposa Serra do Sol indigenous territory along the Brazil–Guyana–Venezuela triple border and have maintained a presence in the area across generations. Remarkably, Brazil's northernmost point is closer to every other country in the Americas than it is to Brazil's own southernmost point, underscoring the country's extraordinary north–south span.
Who First Discovered Monte Caburaí?
Marechal Cândido Rondon led the first documented expedition to Monte Caburaí in 1930, pushing north from Mato Grosso through the Amazon frontier to claim Brazil's northernmost point. His Rondon leadership shaped every decision, from route planning to trail-blazing through dense rainforest using machetes after following indigenous hunter paths.
The expedition logistics were demanding. His team endured harsh living conditions, challenging terrain, and days of difficult hiking before reaching the summit. Once there, Rondon confirmed Monte Caburaí as Brazil's northernmost point, cementing the country's northern border with Guyana.
Despite this historic achievement, the region faded into obscurity after the expedition due to its extreme inaccessibility. Today, modern explorers retrace Rondon's tracks, honoring his pioneering role in Brazilian exploration history. The mountain itself sits within Mount Roraima National Park, on a plateau at approximately 1,000 meters altitude, adding a layer of protected wilderness to its already formidable legacy.
Monte Caburaí rises to a height of 1,465 meters and is located in Roraima at Brazil's northernmost frontier, bordering both Guyana and Venezuela.
The Endemic Plants and Rare Birds Found Only Around Monte Caburaí
Beyond Rondon's historic footsteps lies a botanical and ecological world that's just as remarkable as the expedition itself. Monte Caburaí hosts extraordinary biodiversity you won't find anywhere else on Earth.
Endemic plants and rare birds define this highland:
- Endemic orchids blanket the high plateau, thriving in isolated conditions shaped by Precambrian geology
- Clusia grandiflora grows exclusively here and neighboring Guyana, making it irreplaceable
- Rare birds inhabit the gigantic trees, drawn by invigorating highland winds at 1,000m altitude
Expeditions have collected nearly 4,000 plant samples from this region, uncovering 60 vascular plant species previously unrecorded in Brazil. The tepui's geographic isolation creates natural barriers that drive unique evolution, turning Monte Caburaí into a living laboratory unlike anywhere else in the Amazon. Saxofridericia regalis was recorded at Mount Caburaí for the first time in Brazil, a species previously known only from the highlands of Venezuela, Guyana, Suriname, and French Guiana. Researchers have also described new Bromeliaceae and Eriocaulaceae from the broader Pantepui region of the Guayana Shield, highlighting how much botanical discovery remains ongoing across these ancient table mountains. Much like the undeciphered illustrated manuscript known as the Voynich Codex, which features hundreds of drawings of strange plants that don't exist, the flora of Monte Caburaí reminds us that the natural world still holds discoveries that challenge our existing knowledge.
The Ailã River: Born at 1,465 Meters on Monte Caburaí
At 1,465 meters above sea level, the Ailã River springs to life directly on Monte Caburaí, making its source the northernmost point of Brazil. You're looking at a waterway that flows entirely through Roraima state, carrying water from this ancient Precambrian summit down into northern Brazil's landscapes.
The river also carries the names Uailã River and Rio Ailã in Portuguese, so don't let the alternate spellings confuse you during your research. For those drawn to river ecology, this source offers a rare opportunity to study a high-altitude origin point where water first gathers before shaping downstream ecosystems.
If you're planning a source pilgrimage, you'll be standing at Brazil's geographic northern extreme, where a single mountain simultaneously defines a national boundary and births a river. Monte Caburaí shares geographic and geological similarities with notable regional peaks such as Mount Roraima and Imataka Mountains, placing it within a broader family of comparable Amazonian and Guiana Highland landmarks. The Ailã River's coordinates are precisely documented at 5°16′20″N 60°12′43″W, pinpointing its location within Roraima state with geographic accuracy.
The Garã-Garã Waterfall Hidden at Brazil's Northern Tip
Hidden within the strenuous terrain of Monte Caburaí, the Garã-Garã Waterfall stands as one of the most dramatic features at Brazil's northern tip.
Discovered alongside Monte Caburaí in 1930 by Marechal Cândido Rondon, it carries deep cultural significance as part of Brazil's exploration history.
You'll find it cascading 96 meters along the Maú River, which forms the Brazil-Guyana border.
Its ecotourism potential is undeniable, offering adventurous travelers breathtaking rewards after challenging climbs through dense forest.
Key highlights include:
- 96-meter drop producing powerful, continuous rapids
- Border location along the Maú River between Brazil and Guyana
- Rich biodiversity featuring hundreds of bird species and endemic plants like *Clusia grandiflora*
This hidden gem exemplifies the raw, untouched beauty defining Brazil's northernmost landscape. Monte Caburaí sits at 1,465 meters above sea level, placing the waterfall and its surrounding environment within one of the most elevated and remote regions of northern Brazil. The broader region sits within Uiramutã municipality, located in the state of Roraima in northern Brazil.
Why Is Monte Caburaí So Hard to Reach?
Reaching Monte Caburaí isn't just difficult—it's a serious expedition that demands physical endurance, expert navigation, and careful logistical planning.
Access challenges begin immediately: you're facing a 5-day trek through dense lowland and highland rainforest, where slippery roots, fallen logs, and relentless humidity test every step. Daily temperatures hit 35°C, and unpredictable rain turns already treacherous trails into obstacle courses.
River crossings add real danger, requiring you to balance across slippery trunk bridges over deep igarapés. You'll need a machete to blaze new paths through dense vegetation, plus GPS, compass, and guides who know the terrain intimately.
Cultural interactions with Ingarikó guides aren't optional—they're essential. Their survival knowledge keeps expeditions moving safely through one of Brazil's most unforgiving and remote environments.
What Makes Monte Caburaí Unique Among Brazil's Four Extreme Points
Once you've pushed through that grueling 5-day trek, you begin to grasp why Monte Caburaí isn't just another remote peak—it's Brazil's northernmost point, standing at 5°16′20″N, 60°12′43″W on the Guyana border in Roraima state.
Unlike Brazil's other three extreme points, Caburaí carries distinct qualities:
- Geopolitical symbolism: It marks an international boundary atop a 1,465-meter Precambrian plateau, where Brazil's iron border pole and flag define sovereign territory.
- Indigenous stewardship: The surrounding Roraima highlands remain under traditional indigenous guardianship, preserving biodiversity unavailable elsewhere.
- Hydrological origin: It births the Ailã River, directly feeding the Amazon basin from Brazil's northern edge.
No other extreme point combines border significance, living ecosystems, and river origins so precisely in one location. The summit itself was opened to non-military visitors only in 2005, making public access to this sovereign landmark a relatively recent development.
