Tabwémasana is the highest mountain in Vanuatu and the highest point of Espiritu Santo, rising to 1,879 m. It is a peak in the Sanma region of Oceania, on the western side of the island and close to the Coral Sea coast.
Also known as Mount Tabwemesana, Tabwemasana and Kalnas Tabvemasana, it is the highest peak in the Mount Tabwemasana range and the highest of 92 named peaks in that range. The mountain is isolated, steep, and rarely climbed, with access usually arranged through local villages and guides.

Tabwémasana lies in the Mount Tabwemasana range on Espiritu Santo, in the Sanma region of Vanuatu. It is the country’s highest point and the highest peak in the range. The mountain sits in the western part of the island, about 10 km from the Coral Sea coast, with steep forested slopes and a remote interior setting.
The surrounding landscape is rugged and largely uninhabited today. Older settlement once existed on the slopes, but the mountain is now approached from the coast. The terrain around the peak is shaped by river valleys, dense tropical vegetation and sharp elevation gain, which makes travel slow even over short distances.
Tabwémasana rises above a cluster of nearby peaks, but most are much lower. The closest named summits are:
These neighbours show how dominant Tabwémasana is in the local landscape: it is higher than every nearby peak listed here, and its prominence equals its full elevation, so it rises directly from the surrounding terrain.
From the summit area, the highest peaks within 25 km are spread across Espiritu Santo. The main names to look for are Pic Santo (1,704 m, 14.4 km southeast), Matsimen (1,586 m, 12.4 km south), and Naenpoé (1,566 m, 10.1 km south). Other high points include Batounlamévous to the southeast, Boutvatano to the northwest, and Talapon to the south.
These peaks are lower than Tabwémasana, but they help define the mountain skyline. On a clear day, the summit should give a broad sense of the island’s western highlands and the ridges that run toward the coast.
Mount Tabwemasana is the highest peak in its namesake range, which contains 92 named peaks. Tabwémasana is the range high point, and the range itself is part of the wider sequence Melanesia > New Hebrides > Espiritu Santo > Mount Tabwemasana.
Within that range, Tabwémasana stands at the top of the elevation list and also serves as the country high point. Its position at the head of the range makes it the main summit for anyone interested in the island’s highest terrain.
Climate estimates from NASA POWER for 2001–2020 suggest a warm, wet tropical mountain climate around Tabwémasana. At the summit, the warmest month is about 18 °C in January and the coldest is about 15 °C in July. Mean temperatures stay above freezing in every month. Annual precipitation in the surrounding area is about 2,250 mm, with the wettest month around 275 mm in February and the driest about 105 mm in August.
Expect frequent rain, humid forest conditions, slippery ground and fast changes in visibility. In this part of the tropics, heavy showers, swollen streams and muddy tracks are the main weather hazards, especially on steep slopes and in the wet season.
Because temperatures stay above freezing all year, the main planning factor is rainfall rather than cold. The drier period is usually the better time for a climb, with August standing out as the driest month in the climate figures and February the wettest. Even then, mountain weather can change quickly, so a dry spell does not guarantee easy travel.
For a visit to Tabwémasana, the most practical window is generally the less rainy part of the year, when river crossings are easier and the track is less slippery. On this island, a flexible schedule is useful because tropical showers can return at any time.
The slopes of Tabwémasana are covered in tropical mountain forest and wet lowland-to-mid-elevation vegetation, with thicker forest in the valleys and more open ground near the highest ridges. The island’s isolation supports a distinctive mix of plants and animals, and the mountain is known as the only home of the tree species Metrosideros tabwemasanaensis.
Birdlife, insects and forest reptiles are typical of this kind of environment in Vanuatu, and the steep, humid terrain favours mosses, ferns and dense undergrowth. The combination of rain, shade and remoteness makes the mountain a stronghold for native forest species.
For a climb of Tabwémasana, a local guide is strongly advisable and commonly required in practice because the route is hard to follow and the terrain is steep. In Vanuatu, visitors usually arrange mountain trips through local tourism contacts and village-based guides rather than through a large alpine infrastructure. The emergency number for mountain rescue is 115.
Organised ascents usually include boat access to the inland starting point, route finding through river valleys, and a summit push from the base area. Check Yasur and Ambrym volcano alert levels before travelling in the country.
Tabwémasana demands fitness, sure footing and comfort in wet tropical terrain. The climb involves river travel, steep ascent and navigation through forest where the track can be difficult to see. Mud, rain, leeches, heat and sudden stream rises are all realistic hazards, so sturdy footwear and rain protection are essential.
Carry enough water for the day, usually 1.5-3 litres depending on heat and effort, and plan for slower progress than the map suggests. The mountain is remote, so start early, travel with a guide, and use the emergency number 115 if help is needed.
Tabwémasana has two summit tops separated by a hollow, and local tradition treats them as male and female forms that come together at night. The mountain’s slopes were once home to the village of Kerepua, which was moved to the coast in the late 1970s. That relocation helped create the present-day starting point for summit attempts.
The name appears in several forms, including Mount Tabwemesana, Tabwemasana and Kalnas Tabvemasana. Geological structure on the mountain is said to have formed mainly in the Miocene, linking the peak to the older volcanic and uplift history of Espiritu Santo.
Tabwémasana is the highest of 92 named peaks in its range and the highest point of both Espiritu Santo and Vanuatu. Its prominence is 1,879 m, matching its elevation, which means it rises as a fully independent summit. The nearest higher peak does not exist on the island, because this is the top of the range.
Another notable fact is how rarely it is climbed: the summit is reached by very few visitors each year, largely because of the mountain’s isolation and the difficulty of the approach. The mountain also has a strong cultural presence in local folklore, which adds to its identity beyond its physical height.
How high is Tabwémasana? It rises to 1,879 m, making it the highest mountain in Vanuatu and the highest point of Espiritu Santo.
Where is Tabwémasana located? It is on Espiritu Santo in the Sanma region of Vanuatu, on the western side of the island near the Coral Sea coast.
What range is Tabwémasana part of? It is the highest peak in the Mount Tabwemasana range, which contains 92 named peaks.
What are the nearest peaks? The closest named summit is Cotamtam, 1.2 km east at 1,345 m. Other nearby peaks include Taoaloalo, Latouba and Linsoubé.
Is there water on the way to Tabwémasana? The route follows river valleys, so water is part of the landscape, but you should still carry your own supply. For a day on this steep tropical mountain, plan on 1.5-3 litres depending on heat and effort.
How long does it take to climb Tabwémasana? A normal ascent from the base area is about 5-6 hours. The approach is difficult, so the real time can be longer.
Is mobile phone coverage reliable? Coverage in the hills is patchy and depends on the operator. In open places a signal may be possible, but it often fails in valleys and behind ridges. 112 reaches emergency services over any available network, and maps should be downloaded before you go.
