Upper Mustang. The name alone conjures images of a stark, windswept landscape, ancient monasteries clinging to cliffsides, and a culture untouched by time. As a travel enthusiast and seasoned trekker, I’ve had the privilege of experiencing this hidden kingdom firsthand. However, the altitude presents a significant challenge. Many underestimate the effects of altitude sickness, especially when planning a budget trekking adventure to this remote region. This guide, specifically tailored for your Upper Mustang trek in July 2025, will provide you with practical, actionable advice to prevent altitude sickness and ensure a safe and unforgettable journey.
Planning an affordable hiking trip to Upper Mustang doesn’t mean sacrificing safety. In fact, with careful planning and awareness, you can experience the magic of this region even on a cheap Nepal trek. This article focuses on equipping you with the knowledge you need to acclimatize properly, recognize symptoms, and manage altitude sickness effectively so you can focus on the stunning scenery and rich culture.
Understanding Altitude Sickness in Upper Mustang
Upper Mustang’s unique geographical location, nestled in the rain shadow of the Himalayas, makes it accessible even during Nepal’s monsoon season (June-September). However, the high altitude (Lo Manthang, the capital, sits at around 3,840 meters or 12,600 feet) presents a constant risk of altitude sickness, also known as Acute Mountain Sickness (AMS). Unlike other regions of Nepal where the monsoon brings constant rain, Upper Mustang experiences less precipitation, making it a desirable, albeit challenging, trekking destination in July. The air pressure is lower at higher altitudes, meaning there’s less oxygen available. Your body needs time to adjust to this reduced oxygen level.
Why Upper Mustang is Unique
While altitude sickness can affect anyone, Upper Mustang’s terrain and accessibility during the monsoon require specific considerations. The trails often involve steep ascents and descents, and the dry, dusty conditions can exacerbate dehydration, a major contributor to AMS. Furthermore, the relatively limited access to medical facilities in the region means that prevention is paramount. Don’t think that because it’s drier than other areas during the monsoon you’re immune to altitude issues – be vigilant!
Many people underestimate the effects of altitude. I’ve seen experienced hikers, confident in their fitness, succumb to AMS within hours of arriving at higher elevations. Remember, fitness is not a guarantee against altitude sickness. It affects everyone differently, regardless of age, gender, or physical condition.
Acclimatization: Your Best Defense
Acclimatization is the process of allowing your body to gradually adjust to the lower oxygen levels at high altitude. It’s the single most important factor in preventing altitude sickness. Here’s a breakdown of how to acclimatize effectively during your Upper Mustang trek:
The “Climb High, Sleep Low” Principle
This is the golden rule of acclimatization. Ascend gradually during the day, but try to sleep at a lower altitude whenever possible. For example, if you climb to 4,000 meters (13,123 feet) during the day, aim to descend to 3,700 meters (12,139 feet) for the night. This allows your body to recover and adapt more effectively.
Specific Acclimatization Schedule for Upper Mustang
Here’s a suggested itinerary incorporating acclimatization days, ideal for a 10-12 day Upper Mustang trek in July 2025. This is just a sample, adjust it based on your starting point and personal preferences:
- Day 1: Arrive in Kathmandu (1,400m/4,593ft). Rest and hydrate.
- Day 2: Fly to Pokhara (820m/2,690ft). Rest and explore. This helps acclimatize a little before heading up.
- Day 3: Fly to Jomsom (2,743m/8,999ft). Trek to Kagbeni (2,800m/9,186ft).
- Day 4: Kagbeni to Chele (3,050m/10,006ft). Gradual ascent.
- Day 5: Chele to Syangboche (3,800m/12,467ft). Acclimatization Day: Short hike to a higher point (around 4,000m/13,123ft) and return to Syangboche for the night.
- Day 6: Syangboche to Ghami (3,520m/11,548ft). Descent and then ascent.
- Day 7: Ghami to Lo Manthang (3,840m/12,600ft).
- Day 8: Lo Manthang. Acclimatization Day: Explore Lo Manthang, visit monasteries, and hike to nearby viewpoints (e.g., Namgyal Gompa at 4,000m/13,123ft) but return to Lo Manthang to sleep.
- Day 9: Lo Manthang to Drakmar (3,820m/12,533ft).
- Day 10: Drakmar to Ghiling (3,806m/12,487ft).
- Day 11: Ghiling to Chhusang (2,980m/9,777ft).
- Day 12: Chhusang to Jomsom. Fly back to Pokhara and Kathmandu.
Notice the two dedicated acclimatization days (Days 5 and 8). These are crucial. Don’t rush your trek. Spending an extra day or two acclimatizing is far better than risking serious health problems.
Hydration and Diet
Dehydration is a major factor in altitude sickness. Drink plenty of fluids – at least 3-4 liters of water per day. Avoid alcohol and caffeine, as they can dehydrate you. Eat light, high-carbohydrate meals. Carbs are your body’s preferred fuel at altitude. Avoid fatty, greasy foods which are harder to digest. Dal Bhat, a staple Nepali meal of rice, lentils, and vegetables, is an excellent choice.
Recognizing and Managing Altitude Sickness
Early detection is key. Learn to recognize the symptoms of altitude sickness and act quickly. Ignoring symptoms can lead to serious, even life-threatening complications.
Symptoms of Altitude Sickness
Mild symptoms include:
- Headache
- Nausea
- Fatigue
- Loss of appetite
- Dizziness
- Difficulty sleeping
More severe symptoms include:
- Severe headache that doesn’t respond to medication
- Persistent nausea and vomiting
- Shortness of breath, even at rest
- Lack of coordination (ataxia)
- Confusion
- Coughing up blood
If you experience any of these symptoms, especially the severe ones, descend immediately! Don’t try to “tough it out.” It’s not worth the risk. Inform your guide or trekking companions immediately.
Treatment Options
The primary treatment for altitude sickness is descent. Descend at least 500-1,000 meters (1,640-3,281 feet) immediately. If symptoms are mild, rest and hydrate. Avoid further ascent until symptoms have completely resolved.
Medications like Acetazolamide (Diamox) can help with acclimatization. It works by forcing your kidneys to excrete bicarbonate, which makes your blood more acidic and stimulates breathing, increasing oxygen levels in your blood. However, Diamox has side effects, including tingling in the fingers and toes, and increased urination. Consult your doctor before taking Diamox, and be sure to understand the risks and benefits.
In severe cases, oxygen therapy may be necessary. Some tea houses in Upper Mustang have oxygen cylinders available, but don’t rely on this. It’s best to have your own supply or be prepared to descend immediately if you develop severe symptoms.
Budget Trekking in Upper Mustang: Costs and Considerations
Upper Mustang is a controlled area, requiring a special permit in addition to the standard trekking permits. This makes it slightly more expensive than other treks in Nepal, but with careful planning, you can still enjoy an affordable hiking experience.
Permit Costs (July 2025)
As of July 2025, expect to pay around $500 USD per person for the Upper Mustang Restricted Area Permit for the first 10 days. After 10 days, it’s an additional $50 USD per day. You also need an Annapurna Conservation Area Permit (ACAP), which costs around $30 USD.

A cheap Nepal trek to Upper Mustang is achievable by opting for basic accommodation, eating local food, and carefully managing your expenses.
