Manaslu Expedition

Manaslu was first climbed on 9 May 1956 by Toshio Imanishi and Gyalzen Norbu as part of a Japanese-Nepali expedition led by Yuko Maki. They reached the summit via the North-East Face, which remains the main climbing route used by most expeditions today. And because of this early Japanese strong involvement, many people say that, just as the British consider Everest their mountain, Manaslu has always been a Japanese mountain.

After this first ascent, the mountain became a testing ground for serious climbers. Manaslu attracted climbers seeking new challenges and more technical routes.

• In the 1970s, Japanese teams went back to explore harder routes like the northwest spur.
• In 1972, Reinhold Messner made a bold solo ascent on the southwest face. It was also no oxygen ascent.
• In the 1980s, more international climbers joined, including the first British ascent in 1983.
• In 1984, Polish climbers made the first winter ascent via the normal route in extremely harsh conditions.
• Later in that same decade, Jerzy Kukuczka added another demanding line on the East Ridge as part of his quest to climb all fourteen 8,000ers.

Recent milestones and records in Manaslu climbing:

In recent decades, Manaslu has also become a stage for speed records and “firsts” that push human limits. Various lists of Manaslu records mention fast, lightweight ascents in under 24 hours from base to summit and back, as well as national and gender milestones such as early female ascents and first summits by climbers from different countries.

• Fastest ascent (2024): Tyler Andrews from the USA climbed from base to summit in about 9 hours and 52 minutes in September 2024.
• Youngest male (2022): Nima Rinji Sherpa from Nepal is the youngest male to summit Manaslu on 30 September 2022 at the age of 16 years, 4 months.
• Youngest female (2024): Bianca Adler from Australia is the youngest female climber of Manaslu. She summited the world’s 8th highest peak at 16 years, 237 days on September 25, 2024.
• Youngest female without oxygen (2024): Isabella-Maria Haßmann from Germany reached the summit without supplementary oxygen at a young age (25 years 3 days) on 25 September 2024.
• Oldest climber (2025): Carlos Soria Fontán from Spain became the oldest climber to summit Manaslu at 86 years on September 26, 2025.
• Women’s speed record (2025): Tsang Yin Hung from Hong Kong completed a very fast ascent in under 19 hours from base camp in September 2025.
• Sherpa achievements: Sherpa climbers hold many records and have played a key role in Manaslu’s climbing history. For example, on October 3, 2014, Phurba Chhiri Sherpa from Nepal successfully climbed Manaslu for the 7th time.

For Manaslu, the safest time for stable weather and better summit chances is usually spring (March-May) and autumn (September-November). If you ask any guide which time offers the maximum summit window and fewer surprises for mountain expeditions and long route trekking, they will almost always point you to these two seasons and avoid the monsoon and deep winter.

In autumn, most expeditions choose late September and October. The monsoon rain has just ended, so the air is clean, the snowpack has settled, and you usually get long stretches of clear, dry days with excellent visibility. That means more stable summit windows, less daily cloud build‑up, and drier trails on the approach. Nights at base camp and high camps are cold, but conditions on the glacier are generally predictable, which is what we want for safe rope fixing and summit pushes.

Likewise, spring (especially late March to late April) is the second prime season for Manaslu climbing. Days are a bit warmer, the snow can be friendlier to walk on, and there is plenty of daylight for long rotation days and summit bids. On the approach trek, you enjoy blooming rhododendrons and greener hillsides. However, by late May, the weather can become less stable with more clouds and snowfall. Many climbers who prefer slightly warmer conditions at base camp and quieter trails choose spring.

Outside these windows, the mountain is much less forgiving. In monsoon (June-August), heavy rain makes the lower trail muddy and landslide‑prone, rivers run high, and frequent clouds or snowfall higher up make route finding and avalanche risk more serious. In winter (December-February), deep cold, short days, strong winds, and heavy snow on the Larkya La and the upper mountain make the Manaslu expedition journey very difficult. Thus, for almost all climbers aiming for a safer, more predictable Manaslu Expedition, focusing on autumn or spring is the best decision.

Manaslu has a reputation as one of the “easier” 8,000‑meter peaks, but that needs to be understood correctly. Technically, the normal route on the northeast side is not as technical as very difficult peaks like K2 (8,611m) and Annapurna I (8,091m). Most of the climb is on snow and ice slopes of moderate angle until the upper sections, without huge vertical rock walls. This makes it a possible next step for climbers who already have experience on 6,000m or 7,000m mountains. At the same time, it is still a full death-zone expedition. You will spend long days above 7,000m where the air is very thin, the weather is harsh, and the risks are serious. It is not an easy mountain in the everyday sense.

Likewise, if you compare Manaslu to other 8,000ers like Cho Oyu (8,201m) or Shishapangma (8,027m), Manaslu is at a similar level. Many guides say it is a good first 8,000m peak if you already know how your body reacts to high altitude and you are comfortable using crampons and fixed ropes. The climb itself is long but mostly straightforward. You move through glaciers from base camp to Camp I, then climb steeper snow/ice between Camps I-II-III, and finally follow a tiring route to Camp IV. The hardest parts include crossing crevasses, climbing steeper sections, and walking along a narrow summit ridge where you must stay focused and careful on your jumar and safety line.

Where Manaslu becomes serious is in its objective hazards. The mountain is known for heavy snowfall, hidden crevasses, and avalanche‑prone slopes. Several seasons (including 2012 and 2022) have seen tragic incidents linked to snow instability and overcrowding in certain sections. Fatality rates, when you look at historical numbers, are higher than on the very easiest 8,000ers, even though the technical angle is not extreme. That is why we never sell Manaslu to our clients as a safe 8,000er, but as a real Himalayan giant that can be manageable with the right season, professional rope fixing, conservative decisions, and honest self‑assessment.

From a client perspective, Manaslu sits in the middle. It is much harder and more serious than any 6,000m trekking peaks, but not as extreme as the toughest 8,000ers. For a climber with at least one or two solid high‑altitude ascents (for example, Mera Peak, Island Peak, Lobuche East, Ama Dablam, Baruntse, or a 7,000er) and good crampon skills, it is a good first step into climbing above 8,000m. Meanwhile, for someone with only trekking experience and no previous time on fixed lines, it is too big a jump. So, first build your skills on smaller peaks, then try Manaslu when you are truly ready.

For Manaslu, we only take people who have real mountain experience. This is not a beginner climb or something to “test and learn” on the way. Ideally, you should already have climbed at least one or two peaks around 6,000m to 7,000m, such as Island Peak, Lobuche East, or Ama Dablam, and have slept above 5,500m. If your only background is trekking, we normally recommend a technical 6,000m first, then Manaslu next season.

From a technical side, you must be fully comfortable moving in crampons on steep snow and ice while clipped to fixed lines. That means you can use a jumar and descender properly, manage your safety carabiner, and climb or descend 40-50° ice slopes even when you are tired and wearing a heavy boot/personal load. That said, you don’t need to be a rock‑climbing expert, but you do need to handle ladder crossings, crevasse zones, and exposed ridges without freezing up mentally. If you haven’t used this gear before, we expect you to learn and practice on a lower peak before coming to Manaslu.

Likewise, physical fitness is very important too. You should be able to hike for 6-8 hours a day with around 1,000m of ascent, while carrying 10-15kg, and still recover enough to repeat that effort the next day. To add to this, strong legs, good endurance, and healthy knees are very important because you will be climbing and descending steep slopes in double boots at altitude, which exposes any weakness very quickly.

Just as important as fitness is your mindset. The ideal climber for Manaslu is calm, patient, and able to accept delays and changes in plans before personal summit dreams. On Manaslu, you need to handle long waiting periods at Base Camp, possibly 7-10 days of delay, poor sleep, appetite loss, and the possibility of turning back high on the mountain if conditions change. If you can stay positive in a tent during bad weather, listen to your Sherpa and guide, and still follow instructions accurately when you are tired and frustrated, then you have the right mindset for this expedition.

On Manaslu’s northeast face, avalanche and falling ice (serac) danger is very real. Most of this risk is found higher up on the mountain, especially between Camp II, Camp III, and the slopes leading to Camp IV and the summit ridge. The lower part, from Base Camp to Camp I and Camp II, has crevasses and some technical sections, but the bigger avalanche danger starts above Camp II. Between Camp II ( 6,400m) and Camp III ( 6,800m), the slopes look wide and gentle. However, they are not as safe as they seem. These slopes sit below large ice cliffs and snow-loaded faces. After heavy snowfall or sudden warming, these areas can become unstable, and avalanches can happen without much warning.

Likewise, above Camp III, the risk becomes even more serious. Climbers head toward the North Col and then climb two long snow slopes toward Camp IV (7,500m). In this zone, there are big seracs (blocks of ice) above the route. If one of these collapses, it can trigger a large avalanche that sweeps over the exact spots where climbers are hiking or sleeping. Historical analyses of major accidents, including the 2012 disaster and the 2022 avalanche, point to serac collapse and slab release somewhere above or near this 7,400m zone as the trigger, with debris sweeping down over the normal route and hitting Camp III and parts of Camp II. For this reason, climbers and guides treat the stretch from above Camp II to below Camp IV as the most dangerous part of the route.

When you travel with us, our teams closely monitor the weather, especially new snow, wind, and temperature, adjust camp placements to slightly more protected pockets where possible, and avoid camping directly under obvious serac walls. When we have to cross under threatened slopes or below serac bands, we move as fast and efficiently as we can, in small groups, with everyone clipped in and ready, rather than lingering to take photos or rest. As a local operator, this is exactly where we are most conservative with weather calls and where we would rather lose a summit window than push you across a loaded face at the wrong time.

There is a lot of myth and confusion about the real summit of Manaslu, so let’s keep it straight and honest. For many years, most commercial climbing teams did not reach the very top. They stopped a little before the absolute highest point called the fore-summit because this spot was easier and safer, especially in autumn when the snow is unstable. The top of Manaslu is a long, narrow ridge with a few bumps. The fore-summit is one of these bumps.

The real summit is farther along the ridge, and getting there can be dangerous. The path is often very thin, like a knife edge, with steep drops on both sides. Snow can cover the ground and make it even riskier. Because of this danger, climbing teams used to stop at the fore-summit. They would fix ropes only up to that point, put prayer flags there, and treat it like the top. Clients came home with summit photos and certificates, but in strict topographic terms, many of those climbs did not reach the true highest point of the mountain.

But things have changed in recent years. Experts like Eberhard Jurgalski studied photos and maps and showed exactly where the real summit is. Further, in 2021, Mingma G and his team pushed a new line from the fore‑summit to the true summit and proved a safe way to fix ropes all the way to the real top. And since 2022, major databases like the Himalayan Database have started to distinguish between fore‑summit and true‑summit ascents, and many top climbers have gone back to correct their Manaslu record by tagging the highest point.

So what does this mean for you? If you plan to climb Manaslu, you should ask your guide company this important question: Will we go to the true summit or stop at the fore-summit? Also, know about how they define and document a successful sumit. On our side, we aim for the true top when and only when conditions allow a safe, fully fixed route along the final ridge. But if the snow is bad or the ridge is dangerous, it is safer to turn back early.

Base Camp (4,800m)

Manaslu Base Camp sits on rocky ground with huge views of the Mt Manaslu all around. This is where you spend a lot of time during the expedition, so for us it becomes like a small home in the mountains. When you arrive at base camp, everything is already set up for you. You will have your own sleeping tent, a warm dining tent to eat in, a kitchen, toilet tents, and sometimes even a basic shower tent so you can stay as comfortable and healthy as possible over many weeks.

Soon after, we hold the traditional puja ceremony with our Sherpa team, asking the mountain for safe passage before we touch the route. From here, all the climbing rotations start and finish. After going up to higher camps, you come back here to rest, eat well, drink plenty of water, and recover before the next rotation.

Camp I (5,700m)

The climb to Camp I starts just above base camp. First, you walk for about an hour or so on grassy slopes and rocky ground. Then you reach a crampon point where you put on your climbing gear (crampons, harness, and helmet), and clip into the fixed rope. From there, you move onto the glacier. The route takes about three more hours, going around crevasses and crossing short icy sections. It’s not extremely steep, but you need to stay focused and move carefully.

Camp I sits on fairly flat glacier ground and is spread over two levels, a lower and an upper camp, about 100m apart in height. For many climbers, this is the first time sleeping higher up on the mountain. Nights are colder, the air is thinner, and you may hear the glacier moving around you. We usually use Camp I for acclimatization and as our launch point towards the more technical heart of the route.

Camp II (6,400m)

The climb from Camp I to Camp II is one of the most technical and demanding sections on Manaslu’s normal route. It starts off easy, with about an hour of walking on gentle snow slopes. But soon, you enter a more difficult area with broken ice, big blocks (seracs), and crevasses. In this section, you will use your jumar on fixed ropes almost the whole time. There are also a few ladder crossings over deep crevasses, which require focus and balance. Some ice pitches can reach around 60-65 degrees for short sections, so this is where good crampon work really matters.

Camp II is set on a wide, flat snow area above the icefall. It is safer than the lower section because it is more protected from falling ice. From a guide’s point of view, this is an important camp. It is high enough to be serious, but still a place where we can manage risks and keep an eye on the conditions higher up the mountain.

Camp III (6,800m)

The climb from Camp II to Camp III is shorter, but you start to feel the altitude more. The route continues up sustained snow slopes without big technical surprises. There are no major ladders here in a normal season, but you still cross crevasses and snow bridges, always clipped into the fixed rope for safety. Many climbers find this section easier in terms of skills, but it can still be tough. The area is very open, so strong winds and cold temperatures can make the climb harder. On clear days, the sun can also feel very strong at this height.

Camp III is set on a higher part of the mountain, usually on a small flat area cut into the slope. You don’t spend many nights here, but it is an important stop for acclimatization. It helps your body to adjust before you move into the real thin‑air zone above 7,000m.

Camp IV (7,500m)

The climb from Camp III to Camp IV feels very long and tough, even though the distance is not huge. Oxygen is much lower now, and every step on the 50–55 degree snow slopes feels slow and demanding. This section also has more risk from avalanches, so we move carefully and stay clipped to the fixed rope at all times. We choose the right weather and snow conditions before moving through this area.

Camp IV is set high on the high shoulder or small plateau, just below the final summit slopes. Conditions here are very basic. There are small tents, very little space, and not much comfort because of the altitude. When you arrive, you melt snow for water, try to eat a little, rest for a few hours, and get ready for the summit push. Most climbers do not stay long at Camp IV. They usually leave at night or very early in the morning to begin their final climb to the summit.

Summit Ridge – From False Summit to True Summit (8,163m)

Summit day normally starts around 1 AM. from Camp IV. At first, you climb through a few snow basins and short steep sections. These parts are not very technical, but the altitude is extreme, so you must move slowly and carefully using a headlamp. After some time, you reach a high point called the fore-summit. In the past, many climbers stopped here because the next part is more exposed and challenging. But this is not the true highest point.

From the fore-summit, you continue along a narrow ridge toward the real summit of Manaslu. This ridge is often covered with cornices (overhanging snow) and drops steeply on both sides. When conditions are good, ropes are fixed along the route, and climbers move one by one, placing each step carefully.

Even though the ridge is exposed, the views are incredible. On a clear day, you can see the Himalayas and the Tibetan plateau all around you. After reaching the true summit, climbers usually spend a short time taking photos and enjoying the moment. Then, the descent begins. You return the same way, going back to Camp IV, and often continue down to Camp III if you still have enough energy and daylight.
