Pico da Neblina

Pico da Neblina (Portuguese pronunciation: [ˈpiku dɐ neˈblĩnɐ], Mist Peak; Spanish: Pico de la Neblina) is the highest peak in Brazil, 2,995.3 metres (9,827 ft) above sea level, in the Serra da Neblina, part of the Serra do Imeri, a section of the Guiana Highlands on the Brazil-Venezuela border. As determined by a border survey expedition in 1962, its summit lies just within Brazilian territory, at a horizontal distance of only 687 m (2,254 ft) from the Venezuelan border at Pico 31 de Março.

Easiest routeFrom the town of São Gabriel da Cachoeira to Iazinho river by truck, then by boat on Iazinho river, Ia river, Caburaí river and Tucano river, then on a jungle trail with three camps (Tucano, Bebedouro Novo, Garimpo do Tucano) before the final ascent.

As the peak's name suggests, it is shrouded in dense clouds most of the time.[3] It was first ascended in 1965 by members of a Brazilian Army expedition.[citation needed]


Officially, Pico da Neblina is located in the municipality of Santa Isabel do Rio Negro, state of Amazonas. However, the mountain is not directly accessible from the urban seat of the municipality, which is about 180 km (112 mi) away, and federal authority over the national park, the Yanomami reservation and the border security area supersedes municipal authority in all practical respects. The nearest city is actually São Gabriel da Cachoeira, about 140 km (87 mi) in a straight line, from where virtually all climbing expeditions depart.[citation needed]

The mountain is contained in the Brazilian Pico da Neblina National Park; its northern slopes are also protected in Venezuela's Serranía de la Neblina National Park. The twin parks, together with the neighbouring Parima Tapirapecó National Park (Venezuela), form a protected area complex of about 80,000 km², possibly the largest national park system in tropical rainforests in the world. Pico da Neblina is also located within the territory of the Yanomami people's reservation.[citation needed]

Common misconceptionsEdit

Pico da Neblina is often mentioned as being on the exact border between Brazil and Venezuela. This is true for its massif as a whole, but the main summit is wholly in Brazil, 687 metres from the actual border.[4] It is also sometimes mentioned as being the highest point in South America outside of the Andes, but this is not correct either: the title belongs to Sierra Nevada de Santa Marta in Colombia, which is almost twice the height of Pico da Neblina and completely detached from the Andes. However, Pico da Neblina is indeed the highest point east of the Andes range, and therefore of a large portion of the continent. Neighbouring Pico 31 de Março, which is on the precise international border, is also the highest point in Venezuela outside of the Andes.[citation needed]

Elevation measurementsEdit

For 39 years, based on an uncontested measurement performed in 1965 by topographer José Ambrósio de Miranda Pombo, using a theodolite, the elevation of Pico da Neblina was thought to be 3,014 metres (9,888 ft), but a much more accurate measurement performed in 2004 with state-of-the-art GPS equipment by cartographer Marco Aurélio de Almeida Lima, a member of a Brazilian Army expedition, put it at 2,993.78 m (9,822 ft). This was then officially recognised by the Brazilian Institute of Geography and Statistics (IBGE), the federal government's official geographic survey and census agency, which jointly organised the expedition.[5]

In February 2016, IBGE slightly revised again the official altitude of Pico da Neblina to 2,995.30 metres (9,827.1 ft), a 1.52-metre difference. There was no new expedition or field measurement at the time; the new value is simply a mathematical recalculation of the altitude, based on the previously obtained GPS field data, taking into account a newly available, more precise mapping of the Brazilian territory regarding the geoid (the imaginary surface based on the Earth's gravitational field that is the reference for altitudes). This explains why Pico da Neblina and Pico 31 de Março, which are next to each other, had both exactly the same altitude correction.[1]

Geology and topographyEdit

The Neblina Massif is composed of a tilted block of sandstone overlying Precambrian metamorphic rocks. The peak is an impressive sharp rock pyramid or tooth, towering high (when the peak is visible) over the nearby lowlands on the Brazilian side, as the Imeri range quickly rises from only about 100 metres above sea level to about 2,000 metres at the base of the peak in just a few kilometres; from there the peak rises sharply.[citation needed]

The Venezuelan side of the massif is hillier and the altitude gradient to the northern plains is less abrupt, although deep chasms and high walls still exist. Neighbouring Pico 31 de Março can be considered a secondary summit of Pico da Neblina; it has a smoother, rounder shape and is sometimes difficult to be clearly distinguished from Pico da Neblina on photographs, depending on angle and distance. Due to Pico da Neblina's equatorial latitude, while it can be cold on top, sub-freezing temperatures and frost appear to be rare (no permanent measurements are undertaken), and there is no snow. One non-authoritative source gives an average temperature of 20 °C (68 °F) during the day and 6 °C (43 °F) at night.[6]


Pico da Neblina in 1998 seen from the distance, without the usual clouds. The round blue-shaded secondary peak just behind it is Pico 31 de Março.

There is little documentation available today on the peak's discovery, and virtually none of it is authoritative, even though Brazilians only discovered the mountain fairly recently, in the mid-20th century. This late discovery can be understood if one remembers how extremely remote, inaccessible and uninhabited that part of the Amazon region is even today, and that it could hardly be expected that such a high mountain (by Brazilian standards) could be found standing next to the vast, low-lying Amazon Basin, even though it was known that there were mountains in that area. Moreover, as its own name states, Pico da Neblina is clouded and hidden from view most of the time.[citation needed]

All this led to it only being discovered in the 1950s. The exact date and circumstances are obscure and not documented, but a popular story often heard in Brazil says that it was supposedly seen and reported by an airline pilot who overflew it at a luckily cloudless moment. However, the massif was known well before that on the Venezuelan side, where it was called Cerro Jimé. In 1954, eight years before the Pico da Neblina was successfully climbed, the area was visited from the north by an expedition led by botanist Bassett Maguire, who reached the northern summit plateau of the massif and observed the highest peak, then unnamed, estimating it to be between "8,000-9,000 feet". The whole massif was named Cerro de la Neblina, since Maguire and Reynolds considered at the time that the massif constituted a separate formation from the Imeri range to the southeast.[citation needed]

Soon after the expedition, the highest peak, although unclimbed, was named Pico Phelps in honour of eminent ornithologist William H. Phelps Jr. At that time, the peak was thought to lie entirely within Venezuelan territory. During the 1962 Brazilian expedition, it was determined that the highest summit lies entirely in Brazil. The Brazilian expedition renamed the summit peak to Pico da Neblina, causing some confusion with the name Cerro de la Neblina, which is used in Venezuela to refer to the whole massif. The subsidiary summit on the Venezuelan-Brazilian border was named Pico 31 de Março in Brazil, but it is now known as Pico Phelps in Venezuela.[citation needed]

In the 1950s, it was not yet clear whether Pico da Neblina was in Brazilian or Venezuelan territory, and its precise elevation was not yet known. Therefore, it was still widely held for many years after the peak's discovery that Brazil's highest mountain was Pico da Bandeira (2,891 m or 9,486 ft), between the southeastern states of Minas Gerais and Espírito Santo, in a much more populated, developed and easily accessible region. Only in 1965 it was found and became widely known that Pico da Neblina was the country's highest mountain. Pico da Bandeira remains the highest Brazilian mountain outside of the Amazon region, and the third-highest overall, after Pico da Neblina and 31 de Março.[citation needed]


Due to its location in a national park in a border area that is also part of Yanomami territory, access to the area is restricted and depends on a special permit by the Chico Mendes Institute for Biodiversity Conservation (ICMBio), the Brazilian government organisation responsible for national parks. The permit can be obtained at ICMBio's office in São Gabriel da Cachoeira, but all climbers must take an accredited local guide. A four-day trek each way should be expected, three of which consisting of a jungle trek in the rainforest that can be as hard and challenging as the climb itself. Rescue is close to impossible in the area.[citation needed]

Onchocerciasis or "river blindness," a parasitic disease that can cause permanent blindness and is transmitted by a black fly, is endemic in the area, albeit with a low incidence; malaria and yellow fever transmission are also possible. Therefore, climbers are advised not only to take the utmost precaution in avoiding insect bites but also to discuss preventive and/or therapeutic strategies with qualified physicians who are familiar with tropical diseases.[citation needed]

Robson Czaban, a Brazilian photographer who climbed Pico da Neblina in 1998, reports on his adventure account (in Portuguese) that there are always some gold panners on a small plateau just below the peak, at about 2,000 metres (6,600 ft), called Garimpo do Tucano, which serves as the base camp for the last and steepest part of the climb. While the panners' presence there is technically illegal, they are widely tolerated by Brazilian authorities, and Czaban speculates that this would be because in such a remote area, they are believed to watch the border and nature better than the park rangers and the army would have the means to do. Czaban reports them to be very friendly and helpful.[citation needed]
