Valley of Flowers Trek AMS Risk Calculator

Govindghat to Ghangaria in one day is a 4,200ft gain — watch for symptoms that evening. Hemkund Sahib at 14,107ft is the real AMS risk point. Acclimatise at Ghangaria for a full day before Hemkund if feeling unwell.

The primary risks on Valley of Flowers Trek are: AMS on Hemkund Sahib day — 14,107ft is a significant altitude for many trekkers, Slippery trail conditions in monsoon rain — trail is wet most days, Flash floods on Pushpawati river trail during heavy monsoon rain, Getting caught inside the valley after hours — park closes at 5 PM. Your operator should brief you on each of these before departure.

Diamox (Acetazolamide) is worth discussing with your doctor if you plan to attempt Valley of Flowers Trek (14,107ft). 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.

This trek is safe for solo trekkers. Trail is well-marked, populated with other trekkers and pilgrims, and has tea shops throughout. No technical sections. Very beginner-friendly except Hemkund Sahib day.
