Location and surroundings
Mount Ayanganna belongs to the Pacaraima Mountains, within the wider Guiana Highlands and Guiana Shield. It is in Guyana, in the Cuyuni-Mazaruni region and the Karambaru - Kukui River - Pipillipai district/county. In national terms it ranks as the 3rd highest named peak in Guyana; within the range it is far below the highest summit, but still among the taller tepuis.
The mountain rises out of rainforest and then breaks into stepped slopes and plateaus. Lower slopes carry tall montane forest, while higher, poorly drained surfaces support lower forest and bromeliads. The terrain is remote, humid, and cut by steep changes in height rather than by broad alpine valleys.
Neighbouring peaks
The nearest named peaks and passes give a sense of how isolated Mount Ayanganna is within the eastern Pacaraima Mountains. It is higher than all of the nearby summits listed here, and the closest one is still several kilometres away.
- Ayanganna Mountain — 718 m, 6.1 km east
- Kuiwa Mountain — 702 m, 12.5 km southeast
- Uitu Mountain — 968 m, 18.0 km southeast
- Caburai-tepe — 1,465 m, 27.7 km southwest
- Kukui Mountain — 757 m, 30.5 km west
- Monte Mundico — 1,620 m, 32.7 km southwest
- Semang Peak — 273 m, 32.7 km northeast
- Amakokopai Mountain — 819 m, 35.0 km west
Among these, Monte Mundico is the highest nearby summit, but it is still well below Ayanganna’s 2,041 m. The mountain therefore dominates its immediate surroundings in both height and prominence of relief.
The view from the summit
Within 25 km, the main high points are Uitu Mountain at 968 m, 18.0 km to the southeast, and Caburai-tepe at 1,465 m, 27.7 km to the southwest, which lies just beyond that radius. Kuiwa Mountain and Ayanganna Mountain are lower and closer, so they would appear as part of the surrounding ridge country rather than as equal summits.
From the top, the view is likely to be dominated by forested ridges, broken tepui steps, and the broad rainforest cover of western Guyana. The nearest giant of the range, Monte Roraima, is much farther away, about 85 km to the west, and is not part of the immediate summit panorama.
The range
Mount Ayanganna is part of the Pacaraima Mountains, a range that spans Brazil, Guyana, and Venezuela. The range’s highest peak is Monte Roraima at 2,719 m, about 85 km west of Ayanganna. The Pacaraima Mountains contain 646 named peaks, and Ayanganna ranks 46th by elevation among them.
This range forms part of the broader tepui country of the Guiana Highlands. Ayanganna is notable as the easternmost tepui above 2,000 m, which places it near the edge of the highest plateau country in the Guiana Shield.
Climate and weather
Climate data for the summit are estimates from NASA POWER monthly means. At the top, the warmest month is about 16 °C in March, and the coldest is about 15 °C in January. The surrounding area receives about 1,750 mm of rain a year, with the wettest month around 285 mm in June and the driest about 65 mm in March.
At this latitude and height, expect frequent cloud, heavy humidity, and fast changes in visibility. Slippery rock, saturated forest, and sudden downpours are the main hazards, especially on steep slopes and on the poorly drained upper plateaus.
Best time to visit
All months are above freezing at the summit, with mean temperatures staying around 15-16 °C. The relatively drier period is around March, while the wettest conditions come in June. For walking and camping, the less rainy months are usually easier, but in this region showers can still arrive at any time.
Because the mountain is in the humid tropics, the best window is generally the period with lower rainfall and firmer ground. Even then, expect wet forest, muddy approaches, and cloud on the upper slopes. Good rain protection and time for delays are essential.
Nature and wildlife
The lower slopes of Mount Ayanganna carry tall montane rainforest, while higher levels shift to medium-canopy high-montane forest. Above about 1,100 m, the mountain breaks into flat steps with poorer drainage, where low forest and terrestrial bromeliads become more common. This is classic tepui terrain, with sharp ecological changes over short distances.
Amphibians and reptiles from Ayanganna have been surveyed, and the mountain is fully within Guyanese territory and surrounded by rainforest. In general, visitors should expect humid forest species, mossy rock, and a landscape shaped more by water and drainage than by snow or ice.
Guides and organised ascents
For a remote tepui like Mount Ayanganna, a certified guide is sensible even though the mountain is not a technical alpine peak. The terrain is isolated, wet, and route-finding can be difficult in forest and on stepped rock. In Guyana, visitors usually look to the national tourism sector and local expedition operators in the country’s interior for arrangements, while the army and other official groups have also used the mountain for organised climbs.
Guided trips in this kind of country usually include transport, local logistics, food, camping support, and help with river or forest travel. Costs depend on trip length, group size, and how much equipment and carrying support is needed. For a mountain this remote, planning matters more than climbing grade.
Safety and preparation
Mount Ayanganna demands preparation for humid tropical mountain travel: steep forest, slippery rock, heavy rain, and limited access to help. Carry reliable rain gear, navigation tools, and enough food and water for delays. The interior is very remote, so self-sufficiency is important even on a short trip.
The emergency number for mountain rescue is not a separate service here. In Guyana, call 913 for ambulance, 911 for police, and 912 for fire. Because response in the interior can be slow, prevention and conservative planning matter more than relying on rescue.
History and name
In 1966, the national flag of Guyana was raised on Mount Ayanganna to mark independence, and the ceremony has been repeated yearly by members of the Guyana Defence Force. The army headquarters in Georgetown is also named after the mountain, showing its place in national symbolism.
In 1992, the expedition included a first female soldier, and on 1 November 2005 a group of 28 women soldiers climbed the mountain in two days. The name is widely used in both the mountain and military context, and the mountain is sometimes referred to as Monte Ayanganna.
Interesting facts
Mount Ayanganna is the easternmost tepui above 2,000 m. It is also the 3rd highest named peak in Guyana and the 46th highest named peak in the Pacaraima Mountains. The nearest much higher landmark in the range is Monte Roraima, 85 km to the west.
Another notable fact is its stepped structure: the mountain rises in stages, with forested slopes below and flatter, less well-drained plateaus above. That shape is typical of tepui landscapes and helps explain the sharp ecological zones on the mountain.

How high is Mount Ayanganna? It rises to 2,041 m.
Where is Mount Ayanganna? It is in Guyana, in the Cuyuni-Mazaruni region, within the Pacaraima Mountains of the Guiana Highlands.
What is Mount Ayanganna’s rank in Guyana? It is the 3rd highest named peak in Guyana.
What is the nearest higher major peak in the range? The highest peak of the Pacaraima Mountains is Monte Roraima, about 85 km west.
Is there water on the way to Mount Ayanganna? The mountain is in a very wet rainforest region, but you should still carry your own supply. For a day out, plan on 1.5-3 litres depending on heat and length, and treat any collected water carefully.
How long does it take to climb Mount Ayanganna? A documented expedition in 2005 took 2 days for a group of 28 soldiers. Real times vary with route, weather, and load.
Will my mobile phone work on Mount Ayanganna? Coverage in the hills is usually patchy and depends on the operator. On open ground it may be better, but deep valleys and ridges can block signal. 112 reaches emergency services over any available network, and maps should be downloaded before setting out.
