Parang La Trek AMS Risk Calculator

Critical risk. Sleeping at 16,400 ft is dangerous. If symptoms escalate to ataxia or severe coughing at Bongrojen, immediate evacuation down to Kibber is mandatory.

The primary risks on Parang La Trek are: Severe Acute Mountain Sickness (AMS) or HAPE/HACE on the Parang La approach, Crevasse falls on the Parang Glacier during the descent, Hypothermia from crossing the freezing Pare Chu river. Your operator should brief you on each of these before departure.

Diamox (Acetazolamide) is worth discussing with your doctor if you plan to attempt Parang La Trek (18,300ft). 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 5,578m, 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 prohibited. Doing this unsupported is a death wish due to the isolation, river crossings, and glaciated pass.
