Best Time for Rangdum Kanji Trail Trek — Month-by-Month Guide
September. This is the critical window when the dangerous glacial rivers subside to safe levels, allowing passage through the canyons.
Seasonal Verdict
When should you go?
Because this trek involves deep river crossings in narrow gorges and a high glaciated pass, timing is critical. Early summer brings impassable rivers, while winter brings lethal cold. Late summer to early autumn is the only safe window.
