Trek Overview

Everything you need to know about the journey

The Manaslu Circuit is Nepal's most compelling wilderness loop, tracing a complete circle around Manaslu, the world's eighth-highest peak at 8,163 metres through terrain that changes so dramatically it feels like several expeditions rolled into one. The route follows the ancient Budhi Gandaki river valley northward, climbing from subtropical gorges at 700 metres through dense rhododendron and pine forests, past thundering waterfalls and traditional stone villages, before breaking into the high alpine world above 3,500 metres. Culturally, the trail moves through Gurung, Nubri, and Tsum communities whose Tibetan Buddhist traditions have remained largely intact mani walls, centuries-old gompas, and prayer flags strung across glacial ridgelines mark every significant landmark. Because the circuit sits within a restricted area requiring a special permit and a licensed guide, the trail sees a fraction of the traffic found on Everest or Annapurna routes, meaning you will share the path with yak caravans more often than other trekking groups.

Altitude & Safety

Comprehensive health guidance and immediate response tools for the high altitude trekker.

Acute Mountain Sickness (AMS)

What it is?

Acute Mountain Sickness (AMS), often called High Altitude Sickness, occurs when your body doesn't have enough time to adjust to lower oxygen levels at higher elevations. It is a natural physiological response, but one that demands immediate attention and respect. Think of it as your body's signal to slow down and breathe.

Symptoms

Headache

Rapid heartbeat

Breathless

Dizziness

Insomnia

Fatigue

No appetite

Nausea

Severity Levels

mild

Rest at current altitude. Do not ascend further until symptoms clear.

moderate

Immediate descent required (300-500m). Use oxygen if available.

severe

Life-threatening. Immediate emergency evacuation via helicopter.

Prevention Tips

Ascend slowly (no more than 300-500m per day above 3,000m)
Stay hydrated (3-4 liters per day)
Avoid alcohol and sleeping pills
Eat light, high-carb meals
Listen to your body and rest when needed

High-Altitude Pulmonary Edema (HAPE)

What it is?

High-altitude pulmonary edema (HAPE) is a dangerous build-up of fluid in the lungs caused by altitude-related low oxygen, not by heart failure. It usually appears 24-96 hours after a rapid ascent, often above about 2,400 m, and it can occur with or without AMS. Early diagnosis matters because HAPE can progress quickly and may be more rapidly fatal than HACE.

Symptoms

Chest congestion

Rapid heartbeat

Breathless

Dry Cough

Blue Lips

Energy less

Rapid breathing

Breathless at rest

Severity Levels

Possible HAPE

Cough, chest tightness, unusual breathlessness on exertion, or a sudden drop in walking performance after ascent.

Probable HAPE

Breathlessness with mild activity, marked fatigue, rapid breathing, crackles/rales, or clearly reduced oxygen saturation compared with others at the same altitude.

Severe HAPE

Breathlessness at rest, respiratory distress, cyanosis, or pink/bloody sputum.

Prevention Tips

Ascend gradually.
Once above 3,000 m, increase sleeping altitude by no more than about 500 m per night.
Add an extra acclimatization night for every 1,000 m of sleeping-altitude gain.
Avoid overexertion during the first 48 hours at altitude.
Known HAPE-prone trekkers may need preventive medication from a clinician familiar with altitude medicine.

High-Altitude Cerebral Edema (HACE)

What it is?

High-altitude cerebral edema (HACE) is a severe altitude illness in which the brain swells. It is generally considered the end-stage of AMS and is defined by neurologic symptoms, especially altered mental status and ataxia. It is rare, especially below about 4,300 m, but once it starts it can deteriorate rapidly to coma within hours if untreated.

Symptoms

Severe Headache

Drowsiness

Confusion

Loss of coordination

Unsteady walking

Altered behavior

Stupor

Coma in late disease

Severity Levels

Possible HACE

A trekker at altitude develops a severe headache plus confusion, unusual behavior, or clumsy walking. Action: Treat as HACE until proven otherwise. No further ascent. Start descent urgently.

Probable HACE

Clear ataxia, altered mental status, marked drowsiness, or difficulty walking normally. Action: Immediate descent, oxygen if available, and dexamethasone if trained and equipped to use it.

Severe HACE

Stupor, inability to walk, or coma. Action: This is a life-threatening emergency. Immediate evacuation is required. If descent is not feasible right away, oxygen and a portable hyperbaric device can be lifesaving.

Prevention Tips

Ascend gradually and avoid going too high too fast.
Once above 3,000 m, limit sleeping-altitude gain to about 500 m per night.
Add an acclimatization day for every 1,000 m of sleeping-altitude gain.
Do not ascend with worsening AMS symptoms.
Dexamethasone is used mainly for treatment or emergency backup, while acetazolamide is preferred for prevention of AMS during ascent.
