Shrikhand Mahadev Trek AMS Risk Calculator

EXTREME RISK. This trek reaches higher than Everest Base Camp. Pro-active Diamox from Thachru mandatory if prescribed. Emergency oxygen must be carried.

The primary risks on Shrikhand Mahadev Trek are: Extreme altitude (18,570ft — HAPE/HACE), Rock chimney fall risk, Boulder field instability, Monsoon weather at extreme altitude, Exhaustion-induced errors on descent. Your operator should brief you on each of these before departure.

Diamox (Acetazolamide) is worth discussing with your doctor if you plan to attempt Shrikhand Mahadev Trek (18,570ft). 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.

At 5,660m, 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.

ABSOLUTELY NOT. Even during the official yatra, the trail claims lives every year. Always trek with an experienced team.
