What is AMS?
Acute Mountain Sickness (AMS) is a condition that can affect trekkers at high altitudes, typically above 2,500 meters. It occurs when your body doesn't have enough time to adjust to the lower oxygen levels in the air.
The Golden Rule
"If you feel unwell at altitude, it is altitude sickness until proven otherwise. Never ascend with symptoms."
Mild Symptoms
- Headache
- Nausea & Vomiting
- Dizziness
- Fatigue
- Loss of Appetite
- Shortness of Breath
Severe Symptoms
- Shortness of breath at rest
- Inability to walk
- Confusion
- Fluid in lungs (HAPE)
- Swelling of brain (HACE)
Prevention Strategies
Ascend Slowly
Do not increase your sleeping altitude by more than 300-500m per day.
Hydration
Drink 3-4 liters of water daily. Avoid alcohol and smoking.
Acclimatization
Take rest days every 1,000m of ascent.
Medication
Consult your doctor about Diamox (Acetazolamide) before your trip.
Always trek with a guide who is trained in wilderness first aid and can recognize the early signs of AMS.

Yes, it is mandatory. Your insurance must specifically cover trekking up to 6,000m and include emergency helicopter evacuation.
Common Questions
Q: Why choose Gokyo over Everest Base Camp?
Gokyo offers superior panoramic views (4 of the 14 highest peaks), pristine turquoise lakes, and significantly fewer crowds than the main EBC highway, providing a more serene and authentic experience.
Q: What fitness level is required for trekking in Nepal?
A moderate to high level of fitness is required. You should be comfortable walking 5-7 hours a day with a light pack. Cardiovascular training and leg strength are key preparations.

Our guides are trained to spot early AMS symptoms. The primary protocol is to stop ascending, hydrate, and if symptoms worsen, descend immediately. Helicopter evacuation is available for emergencies.
Booking
Q: How far in advance should I book my trek?
We recommend booking 3-6 months in advance, especially for peak seasons (Spring and Autumn), to ensure flight availability to Lukla and the best teahouse accommodations.
Q: What is your cancellation and refund policy?
We offer a full refund for cancellations made 30 days prior to departure. Cancellations within 14 days are subject to a 50% fee. We recommend travel insurance to cover unexpected cancellations.
Preparation

Yes, most teahouses offer WiFi (via AirLink or EverestLink cards) and charging stations for a small fee ($3-$7). Note that reliability decreases as you go higher.

We recommend $25-$40 USD per day for personal expenses like snacks, hot showers, charging, WiFi, and tips for your crew.
