Junglam Trek AMS Risk Calculator

The 17,250 ft pass on Day 3 is a brutal acclimatization test. Hydrate heavily and ascend slowly. If HAPE/HACE symptoms appear, you must immediately descend back toward Hemis.

The primary risks on Junglam Trek are: Drowning or hypothermia in the Jhunglam river gorges, Flash floods trapping the team in the canyon, Severe AMS on Kongmaru La or Zalung Karpo La. Your operator should brief you on each of these before departure.

Diamox (Acetazolamide) is worth discussing with your doctor if you plan to attempt Junglam Trek (17,250ft). 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 5,258m, 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 strictly prohibited. The sheer volume of river crossings makes soloing suicidal if you break an ankle in the gorge.
