Frequently Asked Questions
What is the AMS risk on Mayali Pass Trek?
Extreme risk. The camp at Masar Tal (15,000 ft) is a massive jump. Operators must mandate Diamox and carry emergency oxygen.
What are the main hazards on Mayali Pass Trek?
The primary risks on Mayali Pass Trek are: Falling into a hidden crevasse on the Khatling Glacier, Severe HAPE/HACE due to the aggressive ascent to 15,000+ ft, Rockfall on the steep descent from Mayali Pass to Vasuki Tal. Your operator should brief you on each of these before departure.
Should I take Diamox for Mayali Pass Trek?
Diamox (Acetazolamide) is worth discussing with your doctor if you plan to attempt Mayali Pass Trek (17,388ft). It is not routinely required for healthy trekkers but is recommended if you have had AMS symptoms on a previous high-altitude trip. Never start Diamox without medical advice — it has side effects including tingling fingers and increased urination.
What SpO2 level is dangerous on Mayali Pass Trek?
At 5,300m, a resting SpO2 below 80% is a medical emergency and requires immediate descent. Between 80–85% — monitor closely and do not ascend further. Most acclimatized trekkers maintain 85–92% at this altitude. Carry a pulse oximeter and check readings morning and night.
Is Mayali Pass Trek safe to attempt alone?
Absolutely prohibited. It is suicide to attempt a crevassed glacier crossing without a roped team and local knowledge of the ice bridges.
